Irfanview.

Find it amazing, fast, lets you crop and do the "basic" things you'd want to do with pictures very easily. It's a good idea to customize the settings to your liking though, since in default it loads a lot of non-image formats, and does not loop through folders, instead tries to go through them all, which does not suit me. Whatever floats your boat though, Irfanview probably has it covered. :)
