I help moderate a forum online, and on this forum we restrict the
size of signatures. At the moment we test this via a simple Greasemonkey script I wrote; we wrap all signatures with a <div>, the script looks for them, and then measures the div's height and width.
All the script does right now is make sure the signature resides in a particular height/width. I would like to start measuring the file
size of the images inside of a signature automatically so that the script can automatically flag users who are including huge images in their signature. However, I can't seem to find a way to measure the
size of images loaded on the
page. I've searched and found a property special to IE (element.fileSize) but I obviously can't use that in my Greasemonkey script.
Is there a way to find out the file
size of an image in Firefox via JavaScript?
Edit: People are misinterpreting the problem. The forums themselves do not host images; we host the BBCode that people enter as their signature. So, for example, people enter this:
This is my signature, check out my [url=http://google.com]awesome website[/url]!
This image is cool! [img]http://image.gif[/img]
I want to be able to check on these images via Greasemonkey. I could write a batch script to scan all of these instead, but I'm just wondering if there's a way to augment my current script.
