I am trying to replace the header image with our own but am struggling to figure out what exactly to replace. From reading the posts it seems the Pixture Reloaded header image is 2 images with one of these being repeated.

I pretty new to Drupal and .CSS but I have install Firebug to try and narrow down what needs replaced or disabled, still having trouble.

Can someone explain how to replace the header?

I have created a subtheme using Footheme if that makes a difference
