Every image host sucks, so here is one for users of my site.
You may upload files up to 5 megabytes (for now).
I allow GIF, JPEG, PNG, and PDF files, as well as Adobe Flash and Photoshop files (but good luck getting any reasonably stacked Photoshop file under 5 megabytes).
I don't check the resolution of the file because that would be retarded.
Right now, files are kept forever.

Upload's broken right now. Sorry! I haven't the time to fix it!
