Images need special handling, you have to have a complete set with versions in several different resolutions with the correct file names all collected together in a single directory. The slide source URL is actually this directory, unfortunatly Moodle dosn't allow directory selections from it's file browser, so the source window is set up to allow you to select anything from within the relevant directory and then trim the source url down.
If you read the 'How to use this module' page there is a brief description of how you setup slide sources using images, including the required resolutions and filenames.
