You can use photobucket or photoshack. Copy the direct link into your profile and it'll load up.
I use photobucket for all my pictures as well. I even host my calendars there.
Imageshack is also good if you don't want to have to create an account.

I am having trouble locating where I can post a picture of my toon for my profile picture here. Sorry to waste a space with this but for some ignorant reason, I cant find it!
