How to move a folder (depending on content)

I would like to check folders on my desktop and if they contain only images then move them to an 'image store folder' within the document folder. If the folder contains any other type of file however, I want it left where it is (excluded form the action).
I can't get this to work. Any suggestions?
Thanks
Just to clarify - if a folder contains images but also other files, I want the folder left where it is.
What I am struggling with is how to tell Hazel to:
- move folders that contain images
- unless they also contain other types of files
