But one would think about anywhere in world ya go just burnin/developin the contents of your memory to cd every now and then would the easist. Anyplace that does prints probably does CD at same price - and about as reasonable as ya get... Maybe ya could even/just take your own CDRW disk with and if host, friends (or local printshop) along the way have a PC and burner your home free!
A simple industry std CDRW would be great and the easyest!
