I was bored, so I cross-referenced the this thread and the bestiary.
Monsters which now have pictures:
Al Kharid Warrior
Spider -2- (kind of - the picture is more a black dot than anything else)
Dagannoth Mother (has a picture, but looks old and has a damage splotch)
Arzinian Avatar (there was no monster with the ID given, but searching "Arzinian Avatar" gave three results, all of which had pictures)
I can't find Witches Experiment -3- at all. The ID number at the beginning goes to Witches Experiment -4-, and I couldn't find it by searching the bestiary. It's also not listed in the graphically updated monsters thread.
Thanks I'll edit the list when I have some time.
There is no Witches Experiment -3- in the db, I guess!
I'll add it to the list though as we still need the image for it.
Gotta run, I'll make the edits after!
