There are many image viewers out there but ImageSorter is probably one of the most original ones you can find. This image browser lets you sort your photos according to common criteria like size or name, but also to more original elements such as color. You can arrange photos on the program's interface by color groups, which undoubtedly helps to find photos in a much faster way. What's more, while having color selected as the arranging criterion you can use the program's sphere visualization, a really attractive 3D interface that you can move around with your mouse to browse pictures. ImageSorter doesn't include any other features besides photo viewing. I missed having at least some basic editing tools. Also, I found it quite weird that the program selects files with just a single click, instead of the standard double click used in almost any other software application. Despite being an original approach to image viewers, ImageSorter is probably too basic when compared to other similar tools.
