Attached is a module that styles the IMCE module to match the CKEditor module. This is based on the previous work that Mike the Coder and Danny Joris before him. I made it so that you don't have to modify your theme to get it working, and more specifically, two themes since I'm using admin theme. The only thing you have to do for it to work is to put the "sprites.png" from the CKEditor download into the "images" folder of the module.
