Bill, thanks very much for this script, it will definitely save me some time. That said, a proper crop function is still as necessary as ever.

Two problems:

1. Cropping is not perfectly accurate. In my test, the cropped area is usually a little too low.

2. The resulting cropped image cannot be scaled without ruining the crop. This is part of OG's flawed image placement approach.

Anyway, I just thought I'd mention it. I understand there is work underway to improve cropping in OG.
