2/14 9:56 AM Go to your fanpage. Click on member info. go to message board option and type in your password. There will be a box that says signature and avatar. Put the picture code of the picture you want in the signature box. An avatar has to be 100x by 100x. Resize it to 100x by 100x and upload it to a site, (tinypic.com). Right click the picture, and click on properties. Copy the picture code and put it in the box where it says avatar. Hope this helps!
