Cropping help.

I've looked through the archives, but I can't seem to find this one tutorial on cropping. The user had a very detailed tutorial on getting a variety of good icons by just using one image. If someone can locate this tutorial, I will be forever grateful! Thank you.

P.S. And I think the image she was working with was a model, if that helps.

I use PS7, but the tutorial might have been for PSP..not sure.

Thanks again!
