There's a company out there that lets you sell everything from clothes to postcards to posters to mugs and mouse-mats with a picture of your choice. All you have to do is upload a picture to them, say which products you want and how much mark-up, and they'll do all of the hard work. And the cost to you? Zilch! Zero! Nothing! What's more, once a month they send you a check with your portion of the income, e.g. if the base price on something is $10 and you sell it for $12 they'll send you $2 for each sale! Pretty awesome if you ask me.

One nice thing for security-conscious folks is that they have an option when you are setting up your shop to make it private, which hides it from website search engines and directories - not completely secure but not too bad either.
