Self-Indexed Windows Bitmap Tool

Here's a tool I just finished for PTP2, but also works for TV and VGA (or PTP1).
I've made BMP viewers for TV and VGA before (probably on my website somewhere), but I've just come up with a new way to do the palette that's a whole lot better...
I call it "self-indexed" bitmaps. These are 8bpp (256 color) bitmaps where the palette is specially designed so that the index equals the desired Propeller color. This allows the Propeller to show the image without any processing. Also, you can view the images with Windows directly.
I've also included two dithering algorithms that can dramatically improve the result. I've used Photoshop in the past to do this, but I realize that not everybody has that.
Anyway, here's a tool to create these various bitmaps.
The biggest size you can do with a regular Prop setup is about 160x120 or something in that range. If you have external memory, you may be able to show a larger image.
Installation is easy! Just unzip the enclosed .exe file to anywhere and then run it.
