I tried something out with Amvira just now. At well over 50 images, she's my character with by far the most art.

A lot of that art is by me, and a lot of it is by other artists. If I ever go to commission someone to draw me art with Amvira in it, I primarily want them to see my pictures of her, since I've got a pretty clear image in my mind of what she should look like, and it's very rare that an artist draws her perfectly identical to that image... or makes an image of her that's so good it supercedes what came before. 

As such, I made a second tab for her and moved all but 7 images there. 6 images by me, one by sandflakes, who drew her metamorphosis into balrog form very well.

But, I'm not actually 100% sure... what do you think makes more sense? Having a second gallery with all the non-ref images? or having all the non-ref images be in the main gallery, with the ref images being in a secondary gallery?

I'm certainly going to do this with at least Lydia, too.
