Can someone point me in the direction of further information for this plug-in.

Namely - what is 'update_exif' supposed to do.

If I select a photo and alter its position on the map then select 'update_exif' the plugin reports success, and the image 'last modified' date changes in the directory - BUT NO change to the position of the image on the map.

If I select a photo and alter its position on the map then select 'update_database' the plugin reports success, and the image 'last modified' date does not change in the directory - BUT THERE IS a change to the position of the image on the map.

So 'update_exif' seems to do nothing.

Or am I missing something?
