Oh, I was wondering why the gifs were no longer animating. I have no clue why that happens...I'm going to have to look into making something that makes videos embeddable.
Edit: I can make YouTube videos embeddable automatically, but something tells me you'd rather upload the file here and have it show up.There's also a forum addon which allows you to embed HTML5 video (like WebM), but the process seems to be roundabout: upload file and post; copy uploaded WebM link, edit post and paste link with special [ html5video ] tags around it. Maybe I can edit that addon so it doesn't need the tags, when I find the time.
...Also, don't use Imgur to host image libraries you link to from elsewhere, content for your website, advertising, avatars, or anything else that turns us into your content delivery network....you grant Imgur a non-exclusive, royalty-free, perpetual, irrevocable worldwide license (with sublicense and assignment rights) to use, to display online and in any present or future media, to create derivative works of, to allow downloads of, and/or distribute any such file or content.
It works!Okay, the problem was that some time ago I enabled the "Re-encode potentially dangerous image attachments" option in ElkArte, for obvious reason. Apparently, this breaks animated gifs entirely. Had to disable it again, oh well.
Interesting, Why whould an animated gif be viewed as a "potentially dangerous image attachment"?
