How to slide the header images

Hello @glewe,
The theme doesn’t support slider header images. This feature will be available soon on Pro version.
You can customize the theme creating child theme to make the header images slide. Customize the code in the inc/hook/custom.php inside function photo_perfect_add_custom_header.

Here are some guides in case you haven’t made one before:
