This is the introduction text that gives an overview of the Photo Gallery shown below. The gallery can show any number of images and the number of images per row will vary depending on the screen size. On smaller mobiles in portrait they will either show as a single column of images or more likely two columns. For a full screen desktop view the number of images will probably be five or six, maybe even giving control to the editor.
Additional settings can be implemented to allow titles to be shown and potentially other settings as well.
