Yeah, black background just for images doesn't bother me - only when I have to read white text, I get dizzy... People sometimes use medium-to-light gray color for text on web sites. That helps (at least in my case) a lot. Another method to ease up eye strain is using medium-to-dark grey for background instead of black. Oh well, there are different perceptions of color (including black and white) by different people. Personally, I would never say that
"the worst thing you can do with a color image is to mount it on a light colored board, particularly white". That sounds like a dogma and I am very wary of any and all dogmas...
