I should get on putting one of my own up.Some people have very interesting pictures for theirs.It would be a nice feature if you could click on it so that it would enlarge so a person could see the avatar in better detail
The avatars don't take up much space and they are currently linked to your personal profile page. The personal profile can contain one additional and slightly larger profile picture and a link to your personal home page. A personal home page is really the best way to provide more pictures and details about yourself. There is also a list at http://www.wcha.org/members/ with links to some other member home pages. All of the forum's image attachments currently occupy about 35 MB so disk space is not a big issue yet. Let me know if this doesn't answer your questions.
