Hi *,

I finally succeeded in doing what I wanted by following Lyndel McGee's advice - Thanks, Lyndel! It was a pain, but by far the most efficient possible way. I don't have XP, so I used IrfanView as an image browser. What I thought were duplicates were probably versions with a slightly different color pallette. I got rid of them by editing the references in the CSF file. Where the colors didn't match between images, I was able to correct them by doing search & replace in the BMP files with a hex editor (PSpad). After compiling the CSF file, loading it in ProntoEdit 4 and saving it, the unwanted images seem to be gone. Probably, they were already eliminated during the compilation, since they were no longer referenced in the CSF file.
