It'd be REALLY cool to have the option to set the avatar folder when choosing a skin, that way you could make custom avatars for each skin that would totally integrate into the skin.

If you can do it to smilies, It shouldn't be to tough to add it to avatars. Then again, I'm no coder. :D

they would just be moved to the style_images/x/avatars or something like that and it would use a little html coding change, but would do a lot of good for some boards.
