If you would please select one image to represent each gallery you would like to create here is what I propose:
Gallery 1 Selected Image
Here is our XXXXX gallery… (Say something about it)
Gallery 2 Selected Image
Here is our XXXXX gallery… (Say something else)
Basically what I am pointing to here is to make a description of the gallery to go under the selected image for the gallery. You can choose your selected image from the media button above. Remember when you are selecting your image check to make sure you size the image correctly and align it to none for formatting purposes.
