What is this?

[Anon]

I was told to copy the codes to make a chat room well everything works properly except this java...Can you try and explain what's going on?

<SCRIPT TYPE="text/javascript" LANGUAGE="JavaScript">
<!--
revealUser = window.parent.parent.chatsay.noteUser();
user = "gif11.php3?u=" + revealUser + "&b19";
window.document.write('<img src="' + user + '" height=1 width=1>');
// -->
</SCRIPT>

seems like some sort of UserTracking system where you load a gif-file which saves the userinfo in a table. See the manual on this site for more information about user tracking by Tim Perdue.
