Mangle supports several popular image formats (jpeg, png, gif, etc), and is able to dither and downscale images to fit the screen.
Mangle is also cross platform, and doesn't require an install (it's a standalone executable that you can run from anywhere). It is also "environmentally friendly" by not messing with your registry or modifying your system in any way.
