This program selects a random image from disk, and loads it on the root window. It does this by figuring out which image-loading programs are installed on the system, and invoking the first one it finds.

--verbose

Print diagnostics.

--name

Don't load an image: instead just print the file name to stdout.

directory

The directory to search. The directory will be searched recursively, and all files in it are assumed to be images.
