Kindof an odd request, but does anyone know of a site online that offers easy online image editing for people not too familiar with it?

Here's the deal, I've got a message board on my site. Say that I've got some people visiting it that aren't that great at image editing and they want a cool avatar of their own. I have it set up so they can upload their own avatars, but they have to be under 60x60 pixels. I want to be able to let those people know a place where they can easily edit and resize their graphics so they are uploadable. That way I don't have to make them download an image editor that they may find hard to use.

Is there any such site?

*edit*
Also, is there a good site that offers animated gifs? I found one that acts like it has a lot, but doesn't really.
