I've seen a few blogs that have installed two seperate blogs with the same theme - one which contains their main homepage and one to serve as a photoblog.
On the main page, there's a link to their photoblog which contains a thumbnail image to their most recent photo. However, instead of the whole image resized to a smaller image, the thumbnail is actually a piece, or square, from the image. It seems as if the author is actually able to cut out a square from the full-size image and use it as their thumbnail.
Does anyone know how to pull this off without manually cropping out a small square from every photo that's posted?
(P.S. There are tons of examples of this, but the most common is probably dooce.com)
