Does Mezzmo allow you to cycle through or even randomize the backdrop pictures for a movie?

Right now, I'm having problems even displaying backdrops. My folder structure for movies is as follows...

\movies\1980-1989\A-M\Goonies, The (1985)\
In this folder I have the movie, a trailer, folder.jpg, another jpg (same as folder.jpg) but named the same as the movie, and backdrop1, 2, 3 etc...

Mezzmo is either viewing my folder.jpg or the jpg with the same name as the movie and using that as a background. I see you can go in and change these but if dealing with a large amount of files, I'm looking for something easier. I believe there was a checkbox somewhere that had use backdrops, and that was checked.

Also, the picture that is displayed is about 2 times too large and only shows a part of it. Should I be resizing this in Mezzmo or on the actual picture itself. Sorry - new at this. Love the program though..

Thanks for your help
