PaintShop Pro.
Anctally, there’s some software called humbs Plus, which is meant to be for making thumbnails of photos for the web. I think with the right amount of playing with the settings you could set a maximum height, maximum width, and the desired resolution, then pump in a huge batch of images, numbers, and logos, and they would all be made to fit the size constraints. Print them out, and heep your favourites. Not sure if you can set print size, or you have to set width in pixels?
