The problem with this is that I haven't got a consitent format for my cover art.

As a selection, I've got files like:
cover.jpg
folder.jpg
<name of album>.jpg
AlbumArt_{12345679324789234293}.jpg
AlbumArtSmall.jpg
Cov.jpg
etc... etc...
And that doesn't include derivatives with different capitalization etc

If only there was an option to index given file types in given directories -OR- someone write a nice/better photo viewer app
