Avatar and Signature have rules concerning Size and Weight.. be sure to check the "HELP" for requirments. Look-up each type graphic seperatly .. ie Avatar then Signatures so you know what is allowed on this board.
In your new topic be sure to include most of the basics for size, type, personalization, etc... a Gfx Team member will probably contact you via PM to arrange a TS meeting where you can get down to detail.
Be sure to check our ready made stock avatars .. there are several hundred to choose from.
