I have tried a number of viewers, and I like this viewer as it shows the list of pictures, directory structure, with a large shot of the picture in focus. There are a few areas it could be improved on. It does not appear to be currently supported as the last updates were in 2006. However Ubuntu has it in the repositories, and someone else may take it up.
