Hi Michael,
Unfortunatly not tonite, sorry mate :)
Ill take a raincheck on the beer.
Anything after the ? is called the GET string. Is has NO bearing on the
image whatsoever, unless your image is dynamically created and makes use
of the data passed to it. What is does do is make netscape think that
the data in the SRC="" bit has changed and therefore it cant use its
internal cache.
