I'm using the Graphene theme and when I try to edit the individual image settings in a gallery, the ability to select anything but full size is disabled. I can't even click on the thumbnail, medium, or large options.
I actually started this site on wordpress.com before installing wordpress to my own server and moving everything over. This is what I want a gallery to look like: http://materialityandmags.wordpress.com/abstraction-of-clothing/
And since I'm working with large images, this is what happened here: http://magazines.farahmomin.com/abstraction-of-clothing/
This is something I'm working on for a class and figuring out as I go, so any help would be appreciated.
