JOSM - Geotagged Images -white triangle on current (answered)

With geotagged images if you click on the icon to display the image a white triangle is (temporarily) appended to the icon.

Is this just to highlight the image (as well as the icon turning red) ?
What is the relevance of the orientation the triangle ?
At first sight it looks as if the triangle points to the location.


This is the direction you where looking when the photo was taken. Not many camera models save this information in EXIF, but yours does. The quality varies, some cameras have a magnetic compass, some use GPS to measure the bearing.
