Daniel,
I think the next thing you can do is to make sure the images only use colors in the standard Windows 256 color palette. I know that tools like PaintShopPro have options to convert the palettes of images.
> It is better (grey crosshatch) but not consistent (comes up different colors as I cycle through the color depth). Is there anyway you know of to get it to be consistent? Is this my video driver playing tricks? Thanks.
