Well, I didn't draw the Hellsing Art. A friend of mine did. However, I colored it upon her request as my first coloring assignment. It helped me get back into graphics because I stopped after I got my new computer (didn't have Fireworks, just had Photoshop).
Graffiti's good. I used to use it all the time with multiple accounts, until the accounts got terminated because I was using them only for image hosting. After that, I made a fake index page
http://home.graffiti.net/heavybeat . That site's been alive a long time because of the fake index.
I'm unsure of the bandwidth, but you can store up to about 20mb of stuff. I've had the bandwidth die on several occassions long ago, but that was when I was hosting images for an RPG message board, and about four frequent posters at GT had signatures hosted by me.
