Hello!
I've now looked into that feature more and found out that it should work but it doesn't.
That's what I tried:
1) Taken geo-tagged photo with my Nexus7 appear in the avnotes folder and are placed in the correct position on the map.
2) Copying an external geo-tagged photo to that folder (and restarting OsmAnd) doesn't place it on the map.
3) In OsmAnd's data manager I can find the copied photo and I can run the "Show on map" feature on it.
4) The map opens but I don't know where. Somewhere in no man's land.
5) Displaying that photo in QuickPic and using QuickPic's "Show on map/Osmand" feature opens the photo in the correct position on OsmAnd's map.
Knowing that I'd say OsmAnd doesn't read the geo tag out of the photos it finds in avnotes. Maybe it puts them into an internal database if one takes photos/notes within OsmAnd.
So I'd suggest:
1) Sync EXIF data of new photos in avnotes or in a user defined folder (preferred!) to the OsmAnd database.
2) Use EXIF's "date taken" value whenever a photo's date is shown. Currently it shows the file's timestamp (when file has been copied to avnotes) OsmAnd's data manager.
3) Re-think usability. At the moment you have to perform too many actions to actually view the photo.
I wonder if any OsmAnd developers are reading and comment this forum.
Should I create a feature request?
Best regards,
Andreas
