Other than the JavaScript of timing and rotating images every few
seconds or minutes, is there a way to uniquely load a different
picture every time a browser open a page?
Thanks,
yip

This is a case for a server-side script. It is a matter of a few
minutes and will work for all your visitors (that view images).

The "other than" is rather odd since JS will not work "every time" but
only some times.

Thanks for the reply. If you look at http://www.nyu.edu everytime you
open this url in a browser you will see a new <div> element. Do you
think it is created by a server side script or by some Ajax code? From
my observation I don't see any server side code there. Please comment.

<div id="photography">
        <img src="/v50/images/photos/42/4x2_35980Pg20.jpg" alt="" />
</div>

Server-side code is executed on the server to (typically) generate the
HTML that you see. You can probably do what you're trying to do by using
a combination of a cookie and a server-side script.

The photos appear (and change) when all client-side scripting is off
so a server-side script is probably generating the changed content.
You say you can't see any server code there, but server-side code is
almost always hidden.

There is also a lot of client-side scripting on the page so when that
is active it may also do changing the content. I did not try to find
out what any of it did. Browser sniffing, like glue sniffing, makes
my head hurt.
