I just inserted the German CD and set destination to Stade, called up Info on destination and viewed the HTM file for Parkhotel Stader Hof

All images appeared correctly on the MkIII - the icons, the hotel JPG, everything. The main hotel JPG did appear to get re-sized (squashed) but that will be because I have a 4:3 display, not a 16:9, so the aspect ration for the JPG will be incorrect.
The HTM file becomes scrollable, the image appears below the text and you scroll down to it.

So there we go - let's start making TPD data :-)
