Flickr isn't a site to host stuff like drawings and all, I think? When I first heard about it it was more of a stock photography website, but lately people are just joining and posting whatever. :/ And I don't like it mainly the browsing thing is just... I dunno, lol, I don't like it.
On the other hand, photobucket can get really annoying every time the server overloads and you have to wait to maybe hours before the site starts working again.
Tinypic has been ten minutes in loading and the website still hasn't appeared. I'm giving it up. >>;
