XnView Portable is, put simply, a file explorer that has been especially adapted for image files and developed to be run from a USB key.
XnView Portable features the same design and tools as older brother XnView, which makes it a really convenient photo editor that can be carried with you anywhere. It has support for a few hundred graphic formats as well as other media files, such as AVI and MP3.
The interface in XnView Portable is divided into two sections: the left pane shows the folder structure, while the right one is where the contents of the selected folder are displayed. A double click on any image is enough to open it in full screen and work on it with the program's own tools. XnView Portable is obviously no Photoshop, but you'll be able to do some cropping and resizing, adjust brightness, correct red eyes and other basic editing and retouching tasks.
If XnView is your favorite image viewer, you can now take it anywhere with you thanks to XnView Portable.
