Thanks a lot --but I do have to state my probable inability to carry this out. While I am 100% certain that this would work, and I greatly appreciate the quick reply, I wouldn't know where to begin entering these commands! My experience with Paint.net is limited to pretty basic cutting, cropping, resizing, a little bit of retouching and the like.....The common stuff on the menu bars....
So any further hints would be so helpful. I'm willing to learn -- just need a bit of help about where to start...
Thanks again,
Steve
