This banner contains 1 part : Search box combined with Photo Gallery.
This element is taken from Add Element box -> ST Search with background gallery.
Upload your photos to create a gallery that shows behind the search box. You can adjust rows and columns as you want.
Number of image should be added in to IMAGE IN = Number of Column * Number of Row + 5
It means: If you want to use background with 8 columns and 4 rows you should add number of image = 8 * 4 + 5 = 37 images
