Were does the desktop background information get stored?

I am running Red Hat Enterprise Linux 6 and I can easily change the look of the desktop by right clicking on an empty part of the desktop and selecting Change Desktop Background. I would like to be able to have a cron script change the image displayed depending on the time and day of the week. That would be easy if I knew where the information is stored. But I do not know where that is. If I click Help on that screen, it brings up a window that may have the information, but it crashes very fast before I can read it. -- .~.
