Fool all caching by making it a new image, insofar as (all of the)
caching layers are concerned, with the following syntax:

<img src="http://www.yourdomain.com/yourpath/yourgraphic.gif?randomcharsgohere">

As long as randomcharsgohere is a value your cache layers haven't 
seen before, you're go around *all* caching layers.  I've used 
random numbers for that value before, with success.

This works, because all caching layers believe this image URL is entirely new.
