Create a Media or Masonry Media Grid using images from the Media Library.
Add the “Media Grid” element to your page (for more in depth about adding elements, please see the introduction video).
Once you’ve added the element, the properties window for it will pop up. Here you can select the images you’d like to include in your grid.
There are other settings, including many, many different layouts that you can use. The video below outlines these different layouts.
