But more often than now and then after deleting an imagefile
for a blink of a second the last file in the remaining filelist is shown.
You have to click the fullscreen image and refresh (F5) and/or
the shortcut for fullscreen to have the normal display of images again
- meaning the next image in the list after the deleted one.
When going on and delete more images now and then after deleting another image
the blink of the last image will appear again.
That not very elegant
