You can't. You can only use the premade ones you find around the site.
No,I dont think so.In my old account I have been in neopets for 2 years I didnt get an avatar
There are various secret avatars; about 350. All of them can be obtained in their own special way.Here are some good sites:www.sunnyneo.comwww.avatar.starried.net

If you have a Kacheek as your active pet, you'll get the avatar.
The neopet that you set as your active will appear under your user name and avatar on the boards when you make a post.
You can't get it. It's and edit positioned to look like its an avatar. I would try searching "Fake Neopets Avatars" Copy the HTML code, and paste it on your userpage.
If you wish to get the Ghost Lupe avatar, you must own a ghost lupe.Ghost Paint Brushes cost about 110000Hope this HelpsSpike
