If you do happen to still go for the refresh option despite the forced
image reload (which incidentally netscape only seems to do if you've got
auto-load images on, if you don't have auto-load images but have loaded the
images manually it keeps it's cached copy) then you will probably want to
move from the HTTP-EQUIV method of adding HTTP headers from HTML to a true
HTTP header since you have direct access to them, ie add the following:

Refresh: delay;URL=url

before your

Content-Type: text/html

Just a thought.
