Golfer, (apart from removing dust or scratches from a scanned photo) most of the "editing" you'd ever have to do with photos like that is color-correction and contrast adjustment... and that's really only if you intend to print the pictures.
It's a can of worms unto itself... you need to calibrate your monitor to your printer, or if it is someone else's printer, find out what profile they use and calibrate to that.
I wouldn't worry about it... you will never be able to adjust a photo so that it looks good on everybody's monitor, you have no control over that.
If you're talking about image manipulation (like what Eskimo did
) then Photoshop or an equivalent will do you just fine.
