How to use full screen background images

I want to use scalable full screen background images on 3 different pages of a small site.

I found this info about using jQuery and the fullscreenr plugin, which seems to be what I need:

I have been using Drupal 6 and sub-theming from Fusion up to this point, but really like the responsive, mobile first design of Omega. So I'm new to Omega and Drupal 7.

I can get the fullscreenr plugin to work on a simple HTML site, but I have no clue how to integrate the fullscreenr plugin into Omega. I don't really understand the template structure of Omega, which seems to be my problem.

Is using the fullscreenr plug workable, or is there a better way? I do not understand JavaScript or jQuery. Can anyone point me in the right direction and give me some clues of how to get this done without this knowledge?
