> Firstly, what kind of measurement is ex?  

http://www.w3.org/TR/CSS21/syndata.html#length-units

Relative units are:

        em: the 'font-size' of the relevant font 
        ex: the 'x-height' of the relevant font 
        px: pixels, relative to the viewing device 

I tend to use a mixture of em and px.  Have never used ex but it may have
its uses.

Eric Meyer may have a solution.

My own point of view (purists won't agree but I can live with that): if it's
easily done with a simple, css styled table, why go out on a limb with
complex CSS and background images.  In many cases the difference in download
is minimal, and without the need to download a background image, the
(single, not nested) table approach can be more efficient.  I prefer not to
use background images if all I want is a plain colo(u)r.

If the image is presentational only, make it a background (perhaps ironic
given what I said above)  Otherwise you might try specifying its size in
em's so it will scale up/down as appropriate.  780px is too wide for many
people who still run at a resolution of 800x600.  Why annoy them with
horizontal scrollbars?
