need help with sessions

[Mutt]

I'm using the sig image upload system. I also modified it to make a profile pics upload system. both work great and display the images just like attachment.php does. my problem is, sessions / the who's online page get confused. if you view a thread with a sig image, you location shows up as sig.php instedad of the thread. sig.php is the script that buils the sig image just like attachment.php. anyway, why is it that attachment.php doesn't screw up the who's online page, but this does? how can I get this script to be ignored by sessions? I looked attachment.php and it looks like it resets sessions via the fourm id and I looked at avatar.php and it seems that it bypasses global.php all together to solve this.

is there a way (a variable I can set) so that sig.php does get recorded in sessions? I've been trying differetn things and no luck.

thanks

really need help with this people.

I understand that when you include global.php that the script will update sessions and appear on the who's online page. but the admin scripts include global with showing up on who's online. whats the difference? How do admin script get blocked from online.php?
