[SOLVED] Transparent Background on Pages, not Posts

Wordpress & Atahualpa are up to date.

Site: http://mythiclegions.com/

I would like to have a fully transparent background on Pages, or at least specific Pages, while maintaining the background image on News Posts on the front page of the site.

For an example of what I'm trying to do, on the pages:
http://mythiclegions.com/characters/
http://mythiclegions.com/bio-barbarian/

...I would like to have the images floating directly over the stone background (Center column background). The beige background image is specifically needed for front page News Posts, but I need to get rid of it for separate Pages.

I've tried a number of things (and done plenty of searches) to achieve the desired result, but haven't had success. Any help would be greatly appreciated.
