Well, this is the first mod I have ever done to VB (I'm running 3.03) and it worked right off the bat.

I used some colored dummy images so I could tell what's going onscnreen before I make up my final images.
I never bothered to do a thing with the category strips background, but I'm assuming whatever background I put in Style Manager > All Style Options > Category Strips > Background will appear between my left & right images.
I have one question that I didn't find (sorry if it's been posted). The spacing values of 5px 5px 5px 5px stand for, what? Which number puts the pixel spaces where? Is it left, right, top bottom or similar?
