• I need a simple slideshow for images of different sizes

  - by Darryl Young

  I'm looking for a very basic slideshow which displays images of various sizes. For example, the first image could be a standard 800x600 but the next might be a taller portrait image and so on. The slideshow doesn't need to have any controls. The specification just states that the page will be black and in the centre there'll be the area where images will display. As far as I know, it will be very simple like this - www.jeffcutter.net. I'm limited on time here so I'm not able to look into writing a custom one or anything like that. I just need to get some images displaying like in the example. Thanks in advance, it's much appreciated. Have a great weekend! Regards.

• Drupal: what's the easiest way to let my customer to upload video thumbnails and associate them to v

  - by Patrick

  hi, my customer wants a gallery of videos and images (small thumbnails) and if you click on one of them you can see the picture / video in the overlaying lightbox). Now, I cannot install auto-generating video thumbnails because I don't have access to ffmpeg module on the server. I can only allow my customer to upload these thumbnails by himself. I'm using image and video CCK fields for each node to allow my customer images and videos. However I dunno how should I let him upload thumbnails for his videos. Should I create an additional Image CCK field for this ? Consequently, I should somehow associate the videos with the images in the design and my customer should pay attention to place them in the same order.. this is not very nice solution, but it is the only one that came to my mind so far. Furthermore, I'm using the lightbox I should somehow ignore the video thumbnails and display the videos instead... some tips ? Thanks

• Why this friend function can't access a private member of the class?

  - by Alceu Costa

  I am getting the following error when I try to access bins private member of the GHistogram class from within the extractHistogram() implementation: error: 'QVector<double> MyNamespace::GHistogram::bins' is private error: within this context Where the 'within this context' error points to the extractHistogram() implementation. Does anyone knows what's wrong with my friend function declaration? Here's the code: namespace MyNamespace{ class GHistogram { public: GHistogram(qint32 numberOfBins); qint32 getNumberOfBins(); /** * Returns the frequency of the value i. */ double getValueAt(qint32 i); friend GHistogram * Gbdi::extractHistogram(GImage *image, qint32 numberOfBins); private: QVector<double> bins; }; GHistogram * extractHistogram(GImage * image, qint32 numberOfBins); }

• PHP exec() hangs, Error 500

  - by MRX_II

  So, my plan is to make small thumbnails of URL's with PHP and IECapt. IECapt works well, a nice command line tool, gets the full sized image of specified URL in 1 to 4 seconds. But my problem is to execute it trough PHP. This is the code I've trying to get working: exec('IECapt.exe ' . escapeshellarg($URL) . ' ' . escapeshellarg($Filename)) $URL is of course the URL, and $filename is a simplified version of the URL. Sometimes I get the IECapt to snap the image(trough PHP), but it takes awfully long (30-60s), and in the end I always get a 500-error, with no error messages to tell me what's wrong. Both variables are fine, they work manually with commandline: IECapt http://google.com Google.png My server set-up is IIS7 and PHP5.2.9, if relevant. (Windows Vista, all on my personal computer, so full access.) Any ideas?

• How to I preload images where it actually forces the images to load before continuing (html/javascri

  - by Mr. Flibble

  I want to preload images but ensure they are loaded before continuing. How can I do this? The following does not work as it sends off the load request only, but doesn't wait till the image is loaded. So it is possible that the image isn't loaded when requested soon after. jQuery.preloadImages = function () { for (var i = 0; i < arguments.length; i++) { jQuery("<img>").attr("src", arguments[i]); } } $.preloadImages("img1.jpg","img2.jpg");

• Layering of CSS with z-index

  - by Matt Hintzke

  I have a created a 3 circle venn diagram using pure CSS3 and each circle has a :hover event attached to it. I also have an image of an arrow which is pointing to the center of the venn diagram. I want the arrow to visually appear to be on top of the circles, so I put the z-index higher on the arrow than the circles. The problem now, is that the :hover event does not trigger on half of the venn diagram now because the arrow image is on top, which causes the hover to be on top of the arrow rather than the circle that I want it to be over. So is it possible to make an element have a high z-index visually but not programmatically?

• Can someone tell me why my dataset wont save correctly to the database in simple winforms app?

  - by Mike

  I have been struggling with this all day and I know it is probably something stupid. My code is below. If I call save then exit my program and start again I can save images to my events but if I just call save when I try to add an image and call save again I get a foreign key error. From what I know I thought my save method was updating the database from my dataset so the event associated with the image should exist. Anyway here is my save method... Private Sub Save() Me.Validate() EventsBindingSource.EndEdit() ImagesBindingSource.EndEdit() TableAdapterManager.UpdateAll(EventDataSet) EventDataSet.AcceptChanges() End Sub Am I doing this wrong? Is this enough detail?

• JQuery tools overlay opens at the top of page instead of overlaying in IE, works fine in FF/Chrome

  - by culov

  Here is the sandbox version of my site: http://3.latest.truxmapper.appspot.com/ To reproduce the error, hover over to the toolbar and go to Support -- FAQ. In Chrome/FF, this will work as expected. In IE, the background image will quickly move to the center of the page, but when its time to insert the div over the background image, its inserted on top of the page rather than the center of the page. The plugin example ( http://flowplayer.org/tools/overlay/apple.html ) works fine in IE, so i know it ought to be possible. I've tried messing around with the div placement on the html and with the css to no avail. Does anyone know what could be the problem? Thanks!

• How to create url preview in javascript?

  - by Razor Storm

  Can someone help me with creation of a url preview script in javascript? What I mean is this. Say I have a link on my site, I want the user to be able to mouse over the link, and have an image pop up that shows what the target of the link looks like. Don't worry about the css, I got that working, I just need the actual script to show the image. Currently I am doing it by showing up an iframe that actually renders the page, but this is not scalable and looks ugly. No, having the page display premade images is not an option, since the links will be linking to dynamically generated user content. thanks

• Caching images with different query strings (S3 signed urls)

  - by Brendan Long

  I'm trying to figure out if I can get browsers to cache images with signed urls. What I want is to generate a new signed url for every request (same image, but with an updated signature), but have the browser not re-download it every time. So, assuming the cache-related headers are set correctly, and all of the URL is the same except for the query string, is there any way to make the browser cache it? The urls would look something like: http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297463 http://example.s3.amazonaws.com/magic.jpg?WSAccessKeyId=stuff&Signature=stuff&Expires=1276297500 We plan to set the e-tags to be an md5sum, so will it at least figure out it's the same image at that point? My other option is to keep track of when last gave out a url, then start giving out new ones slightly before the old ones expire, but I'd prefer not to deal with session info.

• Need help specifying a ending while condition

  - by johnthexiii

  I have written a Python script to download all of the xkcd comic images. The only problem is I can't tell it to stop when it gets to the last one... Here is what I have so far. import re, mechanize from urllib import urlretrieve from BeautifulSoup import BeautifulSoup as bs baseUrl = "http://xkcd.com/1/" #Specify the first comic page br = mechanize.Browser() #Create a browser response = br.open(baseUrl) #Create an initial response x = 1 #Assign an initial file name while (SomeCondition): soup = bs(response.get_data()) #Create an instance of bs that contains the response data img = soup.findAll('img')[1] #Get the online file path of the image localFile = "C:\\Comics\\xkcd\\" + str(x) + ".jpg" #Come up with a local file name urlretrieve(img["src"], localFile) #Download the image file response = br.follow_link(text = "Next >") #Store the response of the next button x += 1 #Increase x by 1 print "All xkcd comics downloaded" #Let the user know the images have been downloaded Initially what I had was something like while br.follow_link(text = "Next >") != br.follow_link(text = ">|"): but by doing this I actually send skip to the last page before the script has a chance to perform the intended purpose.

• mysterious difference between rake test and ruby

  - by standup75

  Here is the mysterious: I have a scope which looks like this (in Image.rb) scope :moderate_all, delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") Note that delegates is another scope that I am defining before moderate_all When I leave it like this, I can run my test that checks if an image has been "checked-out" it is not available anymore. I don't put the code of the test, because it does not matter actually. With this code, when I run "rake test" it fails, but if I do "ruby test/unit/image_test.rb" it works! I was thinking I am starting to have a bad day. Then I tried scope :moderate_all, lambda { delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") } And "rake test" passes! So my problem is solved, but why?

• Sending images using Http Post

  - by primal

  I want to send an image from the android client to the Django server using Http Post. The image is chosen from the gallery. At present, I am using list value name Pairs to send the necessary data to the server and receiving responses from Django in JSON. Can the same approach be used for images (with urls for images embedded in JSON responses)? Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a Bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip). Any tutorial to tackle these problems would be much appreciated.

  Every x minutes I grab an image from a network-cam. Now i want to add this picture to an existing video file - on the fly. I don't want to keep numerous image files and then encode them once in a while with e.g. mencoder mf://@${LIST} -mf type=jpg:fps=${FPS} ... The video format/codec doesn't really matter, as long as standard tools (mplayer, ffmpeg, vlc, ...) can handle it. Any ides or suggestions? Thanks in advance!

• Any good class diagram editors out there for Java (not UML)

  - by user85116

  I'm looking for an editor that can create class diagrams, similar to the typical UML class diagram, but specifically for java (so using java terminology; instead of terms like "generalization, realization etc", we use the java equivalents "interface, abstract class, extends etc"). I've looked into UML several times, but each time I've been turned off by the shear amount of "stuff" that comes with UML. I just want to be able to model my java classes quickly and intuitively, without getting bogged down by all the cruft that comes with UML. Preferably, it would come with a source reader that can keep the diagram up to date, and with a few nice features like "show only public methods in this class" etc. As well, it would automatically "know" about the classes in the standard java library, and possibly even be able to read classes from jars. Performance is also a big thing for me, I don't like having to wait 2 seconds for a popup menu to appear, or watch the diagram jerk crazily while resizing an element in the model. What do you think, am I asking too much?

• Custom marker changed to a black rectangle after clicking the marker few times on Google Map v2

  - by RajeevSahu

  Hi, How to avoid displaying black rectangles over the Custom marker. Actually Custom markers changed to a black image rectangle after clicking the marker few times on Google Map. I am using API V2. I am using Nokia N97 to display my google map with Custom markers. I am not sure, but I guess because of wi-fi connectivity, some times the connection lost, so at that moment when I click the Markers, they turned to black image rectangles. Any idea, how to avoid this thing. Thanks...

• Why would I want to have a non-standard attribute?

  - by dontWatchMyProfile

  The documentation on Core Data entities says: You might implement a custom class, for example, to provide custom accessor or validation methods, to use non-standard attributes, to specify dependent keys, to calculate derived values, or to implement any other custom logic. I stumbled over the non-standard attributes claim. It's just a guess: If my attribute is anything other than NSString, NSNumber or NSDate I will want to have a non-standard Attribute with special setter and getter methods? So, for example, if I wanted to store an image, this would be a non-standard Attribute with type NSData and a special method, say -(void)setImageWithFileURL:(NSURL*)url which then pulls the image data from the file, puts in in an NSData and assigns it to core data? Or did I get that wrong?

• ASP.NET Template Selector/Builder - Dynamic CMS

  - by Ugene

  I am currently building my own CMS for various reasons that could take a long to explain... However i am looking for a dynamic solution to create templates for pages within the CMS and all areas must be editable via the administration area, maybe large text areas broken into multiple areas, text and image area on a page etc. Following on from the above i would like to create the following: Create a new page (selecting a pre-defined template like below) http://img525.imageshack.us/img525/9872/nestedpages.png and then upon editing the page it would have created as many text editors required for each editable region or a file upload control for an image area for example. i am thinking of using nested masterpages for the design elements, just unsure the best-practice way to achieve the above (db structure etc) I somehow hope this provides enough information but are happy to answer any questions you may have. Thanks
