For example on the live preview for FlatIron you click the grid display on the index page but in each individual gallery you can either have the blog style display where there's a different photo as you scroll down (example: live preview). But on the live preview when you click the next gallery Rodeo it has the gallery style where there are thumbnails at the bottom and you can click on it to display the next photo (example: live preview).
How do I do that?
