I am building a site for a community theatre and we like the WPMU Nelo theme. We checked the "Do you want to enable Facebook Like in Single Post:" check box and it works. However, the image that goes to facebook is always the same and never the one on the post or page we are Liking.
How do we make the facebook Like button take with it the image from the page we are liking? Especially important when we do a gallery, etc.
