-bc- You not listening to what I'm saying - all you need to do is save a set the way you want the thumbnail to look and use that RSR with the old CR2, you can use any RSR with any CR2 or HR2 (Hair) or PP2 (Prop), it is just a picture. The RSR just has to be the same name, it has nothing to do with anything other than the picture. Trust me, I do this a lot!
