Greyscale album art not working..

After doing some development work with Id3 tags and reading the jpg album art out of them, I realised Rekordbox doesn't work with greyscale art.

Quite a few of my mp3's bought from Beatport and the like have single channel (Luminance) jpg's in them, none of these show up in Rekordbox, it just says no artwork.  Should be simple for your engineers to fix in a future release.  If you want a sample MP3 that has this problem, let me know.
