would be a command to put an image on the map wherever you decide.. it would be something like this..
onmap mapname,imagename;
Mapname would be the name of the map to make sure you get it on the right map.
imagename could be replaced with:
@
[email protected]
or so to set it to a head (instead of displaying the norm image on the map it'd display a cropped / resized head image)
Then there would be..
onmap2 mapname,imagename,x,y;
Same as above, except this one just places it at that x/y on the map and not at where the NPC is located (good for showing a position on a map or something even if the npc isn't at that position)
