Use a white background in the ImageSwiper view, as well as in the file preview window
The current default background setting (black) for the ImageSwiper view and the file preview window is rather stark in contrast to the largely light-colored display.
In addition, black is particularly heavy on the eyes (e.g., pulls your attention), especially when it is used as background to images.
implemented in 2.6

I could see this as an option, for those who like it, but dark backgrounds are much easier on the eyes because there is less glare.
