I tried several different sites for this one.

First I tried a Holiday Monster generator, which I liked until it insisted on adding a message, my name and email, and my friend’s name and email. I used @example.com, just to allow the form to validate (all emails to that domain are automatically discarded), but there was no way to link to the monster I had created.

Next I tried Google Images story generator, which simply flashed each word of my story on the screen in large grey block text. There were no images added to the story.

At a Halloween mask generator I tried “The Joker,” followed by Vladimir Putin, followed by Machiavelli. All of them resulted in a blank mask.

At The Jackson Pollock generator, I made a Jackson Pollock-style painting (which was easier than the physical versions, since it didn’t require any great strength in throwing globs of paint and getting them to make a huge splatter) but I couldn’t link to it.

Finally, the Knuckle Tattoo generator let me make an image and either save it or link to it. “Jam and Toast” didn’t fit without breaking up “toast”; I couldn’t think of anything witty, so I figured that (in the spirit of the original), I’d go with something menacing. Here it is:
nose and chin

Several people pointed out on this thing and on the last one that these image generators could be used for displays and for programs (depending on the type of program). So that’s all well and good provided you find one that actually lets you use what you’ve created.
