Darryl, just getting away from the cropping thing for a minute...I use 'faststone' to preview all my images after
moving them from my camera to PC. It's very quick and so easy. While looking through and deleting (all) the disasters I can press 'C' to copy to a folder of choice (possible keepers) or 'M' to move that image and it saves on doubling up/cluttering hard drives. I can also press 'E' if I get all excited about an image and it'll open/start the file in PS for me.
A very handy allround viewer in my humble opinion.
Thanks @
ameerat42 for mentioning/suggesting it a few years ago -
