Allright, how did I take that picture? It's simple.
-spawn an enemy of these(friend is wrong because they will fly and turn around every second)
-kill it(the creature will fly even after you kill it,because it doesn't have any dying animations
-stand in front of it in free view and take the picture
If you would like to know how to spawn those, you can do it with scripts or with my mod
