GoogleGrab is a clever application for Mac’s and PC’s that will save all of your Google Image results to a folder on your computer. It doesn’t just download the small thumbnails either, it will download the full-size image! There are multiple options that you can choose from including the general size of the image and whether you want to enable SafeSearch. This program may not be useful to you everyday but I am sure you can think of a time or two that you could have used it, I know I can.
