Windows features an embedded image viewer to take a quick look at your pictures.
However, this viewing tool soon falls too short when trying to view certain graphic formats, especially other than the most popular ones like JPG, BMP, PNG or GIF. This is where ImageXtender comes in handy, as it improves Windows standard image viewer so that it's able to open more than 200 graphics formats. At least this is the theory, because I must admit I did have problems to open some files (such as a PSD file from Photoshop) after installing ImageXtender and also rebooting the PC – just in case.
The good thing about ImageXtender is that you don't need to learn how to use it. It patches the standard Windows image viewer, adding new functionality without changing its interface at all. This means you wouldn't even notice that ImageXtender has been installed, if it weren't for the new program group in the Start menu, from which you can change the program's preferences.
ImageXtender looks promising but still fails to display some graphic formats.
