Wow, what a difference! Even if the border is a single pixel, much
better results. I set the border color to grey, which seems to work as
well as black, and am now a happy slideshow maker.
Ideally, you should use whatever color is going to be in the background
when you show the image.
Even better would be if you could blend it with a transparent
background, and show it that way, but that would require an alpha
channel, and I don't think jpeg supports that.
Glad it worked for you,
