487 * And so it happend - ImageMagick is now used to combine my two indexed-color images with transparency. And that works.
488 * Of course it works only if ImageMagick is able to create valid png-images - which you cannot be sure of with older versions (still 5+)
489 * The only drawback is (apparently) that IM creates true-color png's. The transparency of these will not be shown by MSIE on windows at this time (although it's straight 0%/100% transparency!) and the file size may be larger.
