System Utilities » Shell Tools Version : 2.0

This tool adds three new options to your right-click menu on a picture file: convert, print, and thumbnail preview. Converting supports most of the formats you will ever need: GIF, JPEG, BMP, PNG, TGA, PSD, TIFF, PCX, PCD, and more. The thumbnail option is particularly handy when you are in a file open dialog. Clicking on it will open the image in the default program.
