Cool Resizer is a perfect tool for resizing (downsizing) your pictures and photos from digital cameras. It is very easy to use and can resize many image at once. All you have to do is select from one of predefined sizes (small thumbnail, large thumbnail, e-mail, small web, large web) and the program will save all the resized images to a subfolder. All the most popular graphic formats are supported so you won't need other programs.
