I'm horrible at picking this sort of thing, but I can make a suggestion. If possible, convert your pics to B&W (it looks like you scanned them, so you probably can) that will give you a better idea of what they will actually look like in the paper. What you decide is your favorite in color, may not look the way you pictured it in B&W. Also, double check size requirements so you know ahead of time if the picture will get shrunk/cropped. Good Luck!
