A plugin for allowing users to set a custom background on a per-post basis. This plugin hooks into the WordPress custom-background theme feature and overwrites the values on single post views if the post has been given a custom background.
Features
This plugin creates a custom meta box on the edit post screen. From that point, you can select a custom color and/or image. If you select an image, you’ll be presented with additional options for how the image appears on the site.
Requirements
Your theme must support the core WordPress implementation of the Custom Backgrounds theme feature.
