The information from map pins is gone, right? Because it's kind of sad, if you export a topic with a map that has dozens of pins with useful information that just gets lost.
I just checked the source code, and using the "Create HTML file(s)" button already places hotspots onto the smart images. The only problem is that no pin is visibly displayed on the web page (a future enhancement).
If your map image already has identification markers (e.g. room numbers), then maybe you don't "need" pins in order to find the clickable hotspots.
There is one small update I've put in today (not released yet), which will provide the description as a basic tooltip when you hover the hotspot - the formatting in the description won't work without further improvements to the tool.
