If there is writing ont he back the only suggestions are to copy the writing on the back with a good printer. I've been told that the ones that scan are the best for copying (which one of mine does).
Or you can scan the backs and print them out.
The other option might be to get the scrapbook pages with the individual pockets and you could slip the picture in and see both sides. Those come with different size openings to accomodate a lot of different sized pictures.
