hmmm, that's a jpg-version of the jpg-version, only your file is almost double
the size of the file I posted :)

Maybe I could have posted a jpg-version instead of a png.  When I compress it at
a compression-rate of 70 (don't know what that exactly means, but I do know that
70 is a lot :) I get a filesize of almost 130KB, and the quality isn't too bad.
But for those 30KB more, I thought you might wanted to see the png, which looks
almost identical to the rendered bmp-file (I did change it a bit: only 11 colors
were used, so I converted it to a 4bit 16-color image)

cu!
