I know there are a couple of these on-site already (and very good they are!) but I thought for the sake of completeness I'd put one together too in the same PDF format as my other tutorials.

Note that this shows just one method of straightening an image (it works perfectly almost every time for me) but there are others. Also, I believe PS CS/CS2/CS3 have slightly different looking toolbar options for the measure tool but you should be able to use this guide in each of them.

Have fun (well, as much fun as you can when straightening something up anyway)!
