Reply to pritm (.a.t.) mail (.d.0.t.) ru below. I had a similar problem and solved it thus: I had to reduce the number of colors on the image I was using. It appeared to be a black and white map, but contained about 50 shades of almost black and almost white. I reduced this to two colors only (also going from JPG to GIF) so that the borders as well as the areas to be filled each were of a consistent shade. Additionally, it did not work when I specified border colors as black (0,0,0), even though they seem to be of this exact shade in the map file. Instead, I used ImageColorAt() to pick the border color, and now everything seems to work.
