Hi, this was the trouble we had: the png-thumbs remain black (or sometimes even white), but the png beyond is shown without error.
Internet Explorer for Windows and transparent PNGs specifically, or all PNGs? It used to default to specifying black as the background chunk which would lead IE to render transparent images on a solid black background; at some point it was changed to tell ImageMagick to specify a white background color for IE's sake. (Normal browsers continue to display transparency correctly.)
Since we changed back to ImageMagick=false, fortunately most png-thumbs work well, but some (we uploaded before) still remain black.
If you delete the thumbnail files and let them regenerate, how do they look?
