Dear Experts,
Seems like I can't use any of the followings even though I'm running PHP 4.3.2-RC1:
* imagecreatefromjpeg * imagecopy * etc.
Am I right the gd-2.x has already integrated with PHP 4.3.2-RC1 and the gd also has the jpeg integrated?
Or, should do I have to bring in the jpeg-6x myself?
If I need to bring in the jpeg-6x myself, should I install it within the ext/gd sub-dir?
Thing wanted to do: create a separate thumbnail jpeg file from an org. jpeg file. Any better idea?
Please advice.
Thanks in advanced.

Subject: how can php applications use session control to track multiple users?
Dear Experts,
I know you can use session_register to register varialbes, but how do you use sessions for multiple users?
Ex.
$valid_user = $username; // let's say $username has "JSmith" session_register("valid_user");
but if another user (SWhite) logins, then the valid_user now has the value of "SWhite" and the earlier user "JSmith" is gone. So, how do you make the sessions looks like:
JSmith|s:6:"JSmith";SWhite|s:6:"SWhite";
Is this the way how people usually implment to track multiple users?
Any hints would be greatly appreciated!
