Holy cow.  I never realized that before, but it looks like you may be

For images referenced directly within the HTML, you are most likely correct.
However, I plan on loading images dynamically after the page is loaded.

Here's an example of what I'm trying to accomplish...

Let's say we have an online photo archive of 1 million photos.  I'd like to
have a button that replaces the existing image (without a page refresh) by
updating the image src to call a page on the server to return a single
random image from the archive.  I'd also like the photographers name, the
copyright year, the camera information, and the email address of the
copyright holder to be returned with the image.  My thought was to have the
information returned as cookies within the image so that I can publish them
to the page in appropriate places.
