Good tool for light photo editing?

[stan]

I just got my first set of pictures on CD's (vacation pics), and I wan't to
put them up on my web server.

What's a good tool to do some really lightweight editeing on them with?
Mostly I just need to rotate the vertical ones, but I _might_ do just a
little cropping on some few.
