It *may*. It's entirely possible for a web server proxy somewhere to
cache images; "dialup accelerators" like Netzero do this, for
instance. So if you create a web page with one image, it's entirely
possible that someone using NetZero would issue a request for the page
and the image, but have the page come from your server and the image
come from a caching proxy. Further, if your page is static and your
web server sets appropriate HTTP headers, it's possible that someone
using NetZero or AOL could issue a request for your page and see
*both* of them answered from a caching proxy.

(I've spent quite a bit of effort over the past decade explaining to
people why hit counters are useless.)
