In a nutshell, you can animate your avatars now!Read more
Previously I've had the rule against animated avatars in place because many people (myself included) find them incredibly distracting when they're next to text that we're supposed to be reading. There are also accessibility concerns. However, as an admin, I prefer to empower rather than put restrictions on members. Therefore, I've found some scripts and written a couple of arguments to (hopefully) satisfy those who like animated avatars and those who don't.
Essentially, if you do not like animated avatars, you do not need to do anything. All animated avatars for characters are frozen for you. You can play them by clicking on the avatar, click again to stop them. Mobile users will not see gif avatars.
If you do like animated avatars, you need to go to your profile and click on edit profile. Click on the button that is next to Enable Gif Avatars to turn it green. Click save.
If you want to use an animated avatar, you can add one in the regular avatar field as well as your rotator images. Just upload a static image in the static image field as that is what appears for mobiles. If you do not provide a static avatar your character's avatar will be the default image on mobiles. This is covered in the Upload and Add Avatar guide.
Without any experience with them, here are some options to try:
Firefox - Superstop Firefox - change your settings
Chrome - Gif Jam Chrome - Animation Policy Opera - Chrome Extensions (add this extension to add the above solutions) Internet Explorer - change your settings Safari - none currently. Deanimator is an old extension that is still recommended.
If you have any recommendations for gif blockers, please comment here and I will add them to the list!
