An image browser is a utility that can organize and view images quickly and efficiently. Usually they can also perform basic manipulation tasks such as resizing, cropping and re-colouring. A related type of program is an image viewer. The two types of programs are pretty much one and the same, but an image viewer may only be able to view one image at a time, while a image browser can go through an entire directory, or directory tree, of images.
Most image browsers allow good use of meta data to organize pictures and sort through them.
Some open source examples are:
* Eye of GNOME
* Gimp runs on windows as well
