[Plugin: Custom Post Background] Apply background to width & height of post

Excellent post background plugin – but running into a big issue..

Is there any way to apply post background to the entire width / height of the page? Currently, background applies only to the text. We want to use full page background.

any solution to show image (repeat) across the fixed height / width set in the theme?

thanks!
