Use output buffering and use ob_get_length to get the size of the data being
streamed. Note that your images are actually separate retrieves. Most like
you are including <img> tags. Right? As such, you will output a stream of
html and the browser will then make an additional request to get the actual
image. You could determine what images will be requested as you build the
html and then get their sizes and add them to the size of the html you find
in the output buffer.
See
http://us2.php.net/manual/en/ref.outcontrol.php for more info on output
buffering/control.
