Replace one multipage header

Hi folks
On our site http://www.pbycatalina.com we have one header of a half aircraft used for every page and that worked fine until now.
We have built a timeline slider using html, css and jr and would like to use the same header picture and the same size header picture but use a manual slider bar to move the header picture (On only ONE Page)out the left side of the page dragging in the new (but hiding) timeline pictures and content. We understand this can be done quite easily below the header as content but not what we want.
This is (An Example Only) basically how it will react. http://www.jimpattison.com/corporate-info/default.aspx

I suppose my question is: With our slider project complete with both pictures and narrative content…. is it possible to adapt a single page header to accept the slider using the same header picture?
If our slider code would be of value I am happy to include all 1.9mb of the folder.
