MAMEUI Artwork issues- Progetto Snaps

I'm having a really hard time figuring out how to use artwork files for MAMEUI64 (0.147). I'm looking at the Progetto Snaps site, and I'm downloading the files, saving them to the appropriate MAME folder (i.e. Marquees), and renaming the file to Marquees.zip. Nothing seems to be happening, as i can't view anything in the Marquees panel for any of my games.

If someone can help, or point me in the direciton of a tutorial, that would be a huge help

Thanks

Figured out i had to unzip the files...
