Just as an aside, that is a fantastic solution.  I like that a lot.

 > The img src is generated on the fly by Javascript and would always be 
different; this would trigger a 404 error (file not found) on the server 
which the server-side script could intercept, parse, and respond to by 
supplying an existing small (1kb).  Because the img src would change 
each time it was called, I think this would get around the image caching 
problem of a fixed uri.
