Assign backgrounds to posts and pages
The Pro edition supports unlimited background pictures. Assign backgrounds to individual posts or pages to give selected content its own picture while other areas keep their existing options.
Fade between images on pages
Pages can display multiple selected background images with fade transitions. The transition gradually changes the full-screen backdrop from one image to the next.
Choose, preview, and save
Install and activate the Pro edition, then open Appearance > Fullscreen BG Image in the WordPress administration area. Select Choose Image to upload from your computer or pick an image from the media library. Select the image size and click Insert Into Post. A preview appears below the selection area. When the setup is ready, click Save Options and view the website.
