If you're scanning to post online, what is the difference between scanning a print at say 300dpi and resizing, versus simply scanning the print at 72dpi? Also, is screen resolution actually 72dpi, or is it 96dpi?

This is an interesting thread, as I've posted about this very question in the gallery on several occasions. My scans look so bad I've actually recently deleted all my gallery images and stopped posting images altogether. I don't even own a computer, so I scan prints at my parents' house and they have a bottom end Epson and no photoshop or anything, just the software that came with the scanner. I have actually seen a small number of print scans in the gallery that looked quite good, but it's only a handful.
