About the Media Gallery Module Right now in each gallery, when a user clicks on the thumbnail, a larger version will show up in the middle of the screen. With it are arrows to navigate, a "1 of x" caption, a link to start a slideshow, and an x to close it. When I click the image, it takes me to the page of the media. What I want it to do is take me to the next image in the slideshow (like the arrows would have done). I tried looking at the configuration of the Media Gallery Module but there were only options on column and row layout. When I tried to check the settings in the gallery content type, all of the fields were locked and could not be edited. I tried Google for a solution, but not really anything turned up for this specific problem.
You should use Firebug and take a look at the function that gets called, when clicking on the "Next"-Button.(Something like onClick() )

Now take a look at the function, that gets called, when you click on the image.

Now just place the "Next"-Button function into the image. Delete the old one.

The functions are usually in a .js-File. 

This is not so hard, i am a beginner and managed it with the shadowbox.
