Maverick Photo Viewer was designed as an alternative to ACDSee, and proves to be an extremely easy-to-use utility for viewing picture files.

Maverick Photo Viewer can easily replace the Windows Photo Viewer by integrating itself in the Windows shell. And it includes many default keyboard shortcuts, which are the same as the good old ACDSee ones and are fully configurable.

You also have many options for converting pictures into different formats if you choose (36 formats are supported).

All in all a pretty diverse little free image viewing program.
