I guess we need to post a "FAQ" on this ....
Files must be either JPG or GIF format.
The maximum displayable size of an avatar is 80 x 80 pixels. The maximum file size is 64 Kb. If the avatar exceeds either of these limits - it will not show up as an avatar in your message postings.
Rob Babcock is right - you can have an animated GIF file for an avatar - as long as the "viewable" area is <= 80x80 pixels and the total file size is <= 64 Kb.
You can "upload" a file to use as an avatar that doesn't "fit the specs" and the "system" will accept it. It just will not display it as an avatar.
kimbaby - the pic you uploaded for your avatar was too big (100 wide x76 high pixels display area). I trimmed it down (69x76 pixels) and "re-submitted" it. This may take a while (a few hours) to see if it displays. There has been a problem with avatars and they sometimes take several hours for the host server to "recycle" before they show up. If your avatar doesn't show up in 24-hours, PM me.
