Command that would be nice for NPCs..
 

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)

yeah, that would be nice, then we could see the train moving around the map.

Very true, I never really thought of that! Great idea Iraceous
