Hi,

Besides the HTML meta tag, you can also do it in the HTTP headers. In CGI.pm
that would be, for example,

header(-refresh=>'2; URL=http://tux.blackstar.co.uk');

This will generate the following headers.

refresh: 2; URL=http://tux.blackstar.co.uk
Content-Type: text/html; charset=ISO-8859-1

These examples will refresh every 2 seconds.

I don't know how you would change the image, but how about keeping a running
count in a cookie and sending back the corresponding image file?

Just my $0.02.
