[Community] More Icon Trouble (minor issue)

[Ludwig M Brinckmann]

I have now managed to get icons on my map by having a single layer just with 
external icons. This works generally fine. A minor issue is that if a single 
one of the icon images is not available (maybe because I forgot to upload 
it) the map will not show a single icon at all. The legend on the map is 
fine (it shows the missing icon as a broken image), but on the map itself 
all icons silently disappear.
