I seem to have resolved my problems by adding this to my code in a couple of places:
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: post-check=0, pre-check=0', FALSE);
header('Pragma: no-cache');
cache_clear_all();
This doesn't help the problem with the $user context disappearing (I solved that by creating a variable using the user's ip address and storing the info I need there - very crude, but works), but by forcing the browser not to cache the image I am dynamically creating.
Thanks for the suggestion.
