Okay, so I JUST got in a load of comissioned thumbnails to go along with the story series "A New Pet" that I'm writing. Trouble is, for some reason or another, when I try to edit in the pictures, the FA system just completely disregards them.
They're JPEGS so that shouldn't matter, They're not massive even though the instructions say that I can use ANY size image I feel like

Anybody know how to solve this or what the b'jesus is going on cause I really am ready to throw something across the room right now.
It's like its taunting me!

Can anybody help at all?
