I bought a cheap digital camera, and the software for it was all for OS 9. After a few weeks, I figured out that with the combination of Preview, and Grab, I could get most of the functionality I needed.
I download the photos from the camera, and then open them in Preview. It is then possible to "resize" the image in Preview by zooming in and out and rotate the image also. Then, use Grab like a cropping tool.
[Sudo Editor's Note: Although this method of image manipulation is easily out done by the free iPhoto, I found it an interesting exercise in the creative use of the tools found in OS X. Preview also allows you to easily flip the image horizontally or vertically.]
