This Pro tutorial provides the steps to use ACF to select one or more HappyFiles' folders and output the images from the selected folder(s) using HappyFiles shortcode or Bricks' Image Gallery element or img elements in a query loop.

Create folders and categorize images by moving them into the folders.
Step 2
Install and activate ACF.
Go to ACF → Field Groups.
