Change Image onClick Within DIV?

I have a jsFiddle setup to where you will be able to click on the image to the left and when you do it changes the image, but when you click on the DIV as an entirety (expand-one) it does not swap the image out.

I want to be able to click on a DIV (as a whole) and swap out an image that is within the DIV without having only being able to click on just the image.

You can view what I mean here: http://jsfiddle.net/5PDV5/1/

Thank you all! :)
