well i would not tell you to do the same but i would have a very strict position: NO :) i mean, i rather keep some control over the few lame junk i render and put on my website's gallery rather than letting it to spread away on some other medias/sites i do not have any control on. in case of problem (uh oh mister NOW yourpic became illegal because of this or that copyright, patent or whatever or new law that forbid to display obscene strawberries on swimsuits :)) i always can crash my website, delete all the stuff, remove it of whatever. If my work would go away on other shores, the troubles would still come back to me :) i had to react abruptly (though it was not intended or with anger, i swear) to people asking me authorisation to put my lame picture on their good website (while there were better artists around, which i advised them to cotnact instead of me...), and sorry if i sounded harsh. But when you say NO and don't want to debate over anymore, people tend to take it personnally (though it is not the way it was meant)
