I am planning on buying a 32 GB USB flash drive, so that I can transport my pictures back and forth from home and school. The problem is, at home I have a Mac, and at school the computers are PC. Is there anything special I will have to do to make my images work on both computers? I have access to a very high resolution scanner at school, and want to start getting all my old non-digital prints on my new Mac at home. Also, I do my editing on the Mac at home, but will want to print at school from the PC computers. Will this be a problem? Any suggestions?
