I keep track of a lot of Flickr accounts and every so often, I come across a photoset that's just so brilliant, I want to keep a local copy for myself.

Unfortunately, it's rather cumbersome to open each photo individually, save the size that I want, and then rename the file to match the title of the photo.

Even more unfortunate is that as far as I could tell, there wasn't anything for Mac OSX that would help simplify this job. So the only thing left to do was to write Photo Grabbr so that I could use it for myself.
