As a graphic artist who runs through great numbers of images, I've always used some contextual menu for quickly viewing images. Until my Mac Pro, I used Hide Itoh's great series of contextual menus (and found them so valuable that I donated $10 for each of them) but they broke on my Mac Pro. I just 'discovered' ImageViewerCMPlugin and was delighted. Not only does it replace three of Hide's individual CMPs but displays more image types and additionally allows drilling down directories. This is a very valuable item for any professional or enthusiast who sees a great many images and for whom time and simplicity counts. For it's functionality, the price is very modest.
