• Jquery show preloader for every image?

  - by mathiregister

  Hey guys, I've a website with a lot of images: <img class='thumb' src=thumbs/image1.jpg/> <img class='thumb' src=thumbs/image2.jpg/> <img class='thumb' src=thumbs/image3.jpg/> <img class='thumb' src=thumbs/image4.jpg/> I wonder if I can display a loading-div for every single image and when it's loaded the div hides? I'm using jquery for most of my animations. Can i solve that with jquery. It would be cool if every image shows this loading-div centered in the middle of the image. When the image is loaded the div should hide! Is that possible? Thank you for your help!

• How to rotate an image properly in JPanel (Java)

  - by Bruce

  Hi guys, I'm working on rotating a loaded image. I set the graphics on a JPanel and then use standard AffineTransform in order to rotate it, say, 45 degrees. Unfortunately, the image is being cut, if it exceeds the panel area. How may I force JPanel to add scrolls to itself (while loading an image file, I would like to adjust the size of JPanel by adding the scrolls, without adjusting the size of JFrame). Or, in other words, how to correctly rotate the whole image? Thank you in advance for the reply!

• iPhone - Image overlay MapKit framework?

  - by Peter

  I can see with iOS4 you can now tile an image on google maps (Been looking at the TileMap example from apple). This is great as this is what I want to do, but from what I can see I need to know the GEO reference of the image so I can raster the images with the appropriate zoom levels, etc. What I have is an artist image, which is a map of a specific area and I want to overlay this image on google maps. Am I missing something here, but can this be done with a none standard map and having different zoom levels? The main reason why I need to use google maps is because of the GPS functionality, so the user will know where they currently are on the map.

• PHP Image content type problem

  - by Mirko

  Hi everybody, I have a specific problem, and cant get over it. For my latest project I need a simple PHP script that display an image according to its ID sent through URL. Here's the code: header("Content-type: image/jpeg"); $img = $_GET["img"]; echo file_get_contents("http://www.somesite.hr/images/$img"); The problem is that the image doesn't show although the browser recognizes it (i can see it in the page title), instead I get the image URL printed out. It doesn't work neither on a server with remote access allowed nor with one without. Also, nothing is printed or echoed before the header. I wonder if it is a content type error, or something else. Thanks in advance.

• Imagecache for non image CCKs?

  - by Marc Bria

  I'm creating a view with images, videos, audio and documents (books) and I like to shown a picture of each of them in a carousel. Everything works nicely with images and videos as far as we added a image-thumbnail (image filefield) to their CCK but we like to show a default image for audio and documents without changing the original CCK. Is it possible with imagecache (may be with imagecache_custom_code or views_custom_php) or we need to look for a different approach? Thanks for your help, m.

• Create a hyperlink of a slanting image in expression Blend

  - by Tony Bolding

  I am developing a navigation menu in silverlight that has 6 images. As you mouseover each image grows and clicking on an image will take you to a page on the website. The customer I am doing this for decided that straight rectangular images were boring and I showed him a design where I have slanted each image so each one is now a rhomboid shape. Horizontal top and bottom with sides slanting about 30deg from vertical. I have been unable to figure out any way of growing each image on mouseover without putting a white block over the adjacent images. Would be grateful for any pointers.

• Image gallery with a Lightbox in jQuery

  - by Alex

  Hi. I'd like to create a jQuery image gallery of showcased products. It will show one product image at a time, with Next/Previous arrows, and a brief name and price as overlay on the image. If users click it, it will go to the order page. It will have an icon to show a larger, modal version (Lightbox style) of the image with full description, price, and a link to a page to order it. In other words, it's an inline gallery, about 250px X 150px, with next/previous option, but also with a little icon to fire it up in a lightbox type modal window that can have links. Here's an example which doesn't have the inline gallery effect. Here's another, also missing the inline gallery. Is there such a beast as what I'm looking for? Thanks.

• Image in table cell doesn't scale down: using ie8/7

  - by monks1975

  Can anyone help me troubleshoot my website? http://www.andrewstonyer.co.uk/test/ My problem: On IE8/7 if you click on a thumbnail (only 'Pulse' and 'Time Within The Hour' are wired in right now) an overlay appears with detail of that piece. What should happen, and does in Gecko/Webkit, is that the overlay contains a table with a heading, a scaled, centered image, and a nav menu. There is a toggle for text, which pushes up the image cell and makes the image smaller, keeping proportion. I know the overlay looks like ass right now- those are just placeholder colours :) On IE, the image doesn't fit perfectly in the table cell, which means that everything is pushed down outside the window. I can't see the nav menu. It appears to render the image at actual pixel size (in the CSS, the img class element is set to 100% height). The text cell is toggled with jquery, when toggled on in IE, it doesn't appear to 'squeeze' the above cell, which is what I want to happen. Could any experts help? Regards, Jon
