Webmasters Stack Exchange is a question and answer site for pro webmasters. It's 100% free, no registration required.

This may sound ridiculous, but I'm curious as to how this image on imgur is animated: http://i.imgur.com/VnPVF.jpg and yet still appears to be a JPG file, not a GIF.

Is it server side? It's viewing the straight file, and so it can be using any JavaScript or other to fulfill this.

Any ideas?

That's just a GIF image file that had the extension changed to JPG, no javascript involved. –  Mohamed Anis Dahmani Nov 7 '12 at 22:07
    
You can determine the file type by viewing the image meta information in photoshop and other graphic editing programs. If you want to animate a JPG you can use parallax design –  Anagio Nov 8 '12 at 1:11
    
@Anagio ...or the Content-Type HTTP response header as received by the browser (assuming the server is sending the correct headers). In this case "image/gif". –  w3d Nov 8 '12 at 15:45
