Add background to a div based on a Node's Image Field I had a request approach me and am blanking on a smooth way to implement this. We have on content type that on occasion will have a background image in a a div. The image will be a washed out background image behind content. The content authors want to add this page by page using an Image Field. 

How would you implement this?

I'm assuming I can do this through our custom theme -- perhaps a theme_preprocess_page() or theme_process_page()?
You could try BackgroundField:


  BackgroundField started as an extension of the CCK ImageField that
  allows a CSS selector and background attributes to be set for a
  content-type. This is particularly helpful for allowing your node
  authors to add images to a node that are integrated into the theme of
  the site. With the inclusion of the Image field in Drupal 7,
  BackgroundField was rewritten to extend that core functionality.
