2D bmp to 3D conversion... How do you do it?

have been playing around with printing a few 3D logos for friends (college and pro American football teams) and found a program called b2G that will convert monochrome .bmp file to stl file. Then I clean up the stl file in meshlab and reduce the number of triangles to a point that slic3er won't choke on it. Then print it. The whole process is a pain in the butt.

I have attached an example. [attachment 10223 SteelersLogo.JPG]

My question is, Is there an easier way to convert a 2D image into a 3D stl file? Any experience b2g not converting to stl file when you push the button to do so?

P.S.: I realize that copying team logos is frowned upon in most places, but I am just doing a few and will soon move onto to something else. I know that doesn't make it any more legal.

Thanks
