This solution enables you to rotate background images added to the body class using backstretch. Several StudioPress child themes include code which loads a background image via the customizer to display as the site background. This code modification enables you to add multiple images to your child themes images folder and rotate them each time the page is loaded.
The code tweak works on the following child themes:
- AgentPress Pro
- Minimum Pro
- Metro Pro
