Arve -

Getting the value of 'src' here using  
'document.images[0].getAttribute("src")' should return the relative  
path.

The Microsoft guys made a big deal out of the fact that IE8 (in IE8  
'strict standards' mode) will now properly return the relative path  
when 'getAttribute()' is used, but the full path (as you state), when  
the 'property access' version of the call is used. In IE < 8, some  
extra JS to determine base path and then relativize the value would be  
necessary in those browsers.

Cheers,

- Bill
