I have a strange issue. I have an image I have been using in several programs as a background. When I bring it in to SE
the color changes. The Background is a solid black. In SE it turns it into a dark charcoal grey. It also keeps it this dark charcoal grey as well. Any clue as to why?

I do love the program but this sort of bothers me-

Hi,

Yes, it was expected.

Technical explanation:
When displaying JPG image using the 3D card of the computer, the black color (rgb 0,0,0) is converted automatically to "transparent". As this is not intended, We change this black to a very dark gray (like rgb 10,10,10).

This is not perfect, but on most of the cases, this is not noticeable.

If you are using a PNG, as this kind of files handle the transparency, the problem does not occur.

In the past I was converting all JPG to PNG to avoid the issue. The result was nice, but the size on disk was _a_lot_ bigger (especially on presentations with a lot of photos).

So, if you need a very deep strong black (rgb 0,0,0) please use a PNG image.
