Good beginers book for Photoshop CS2?

I've had Photoshop CS2 on my computer for a coulpe months and all I've been able to do is change the size of my picture and change basic brightness and contrast. What is a good book out there that covers the basics of Photoshop that can help me make the most of the program? I'm going to take a beginers photo editing class at the local JC but it doesn't start till summer so I would like something to give me a head start.

Until you find the book you're looking for, check out this website for some excellent tutorials on using CS2 in real life situations.

Books on the subject by Scott Kelby are always a good start.

I'll second the Scott Kelby books. I recently recomended his CS2 book to a couple of local photographers that know almost nothing about photoshop. They LOVE the book.

Thanks for the tips I'll look into those Scott Kelby books today while I'm out.
