Can you post the skin you are using? That will make it easier to make a recommendation.
I'm currently using a modified version of the cddrd.skn file that was in the original download.
Attached is a screenshot of what it is looking like now (see how big the album art is!)

And here is the skin file:

Also I have read that documentation is not your strong point, and that is fine

But is there a list anywere of everysingle parameter that is possible within a skin file or the main jukebox ini? That would be helpful atleast so I could play around with stuff.
Cheers
