Anybody tested if it works adding the thumbnail file? I tried it with images and it did not work. The thumbnail was regenerated in spite of me having put a thumb nail file on the card.

yes. the script mentioned above works perfectly for me. you can adapt it to generate thumbnails for images by changing lines 10-13 and 26 appropriately. find an updated version here:

Why not use this line instead?:

'convert -resize 96x144 -dither -map \"$palette\" \"$file\" PNM:- | pnmtopng 2>/dev/null |'

It seems to work just as well, and it uses one less command (djpeg) and allows for filenames with spaces. What I could not find is the way to generate the correct kind of PNG file directly with convert, without the need for pnmtopng.
