Thanks to all who responded to my bleg on digital photo resizing. Pursuing one of the suggestions offered by commenters, I have downloaded a digital photo resizing program. Unfortunately, the resizing options are listed in terms of pixels rather than inches (i.e. -640x480 pixels instead of 4x6 inches). My question for you experts out there (or just those whose ignorance is less profound then mine): What pixel option should I choose to resize digital 4.5x6 photos to the standard 4x6, so I can then print them out in 4x6 size without cropping (my original objective)?

Thanks!
