An acquaintance of mine gave me his "business card" that looked kind of funny. It was a bit more narrow, printed on good paper, and had a photo that he took on the back side. Being an amateur photographer I thought well that's kind of cool how could I get my grubby little hands on a couple of those. So he told me you could create them from the pictures you post on flickr.com and the company called moo prints them for you.
So, here is the result of the cards I got (only displaying the picture side). On the front side you can squeeze in 6 lines of text and an optional logo. The text can be read from the picture specs too (aperture, lenses, etc).
