Okay lets clarify a few things here.
How do I is a forum where you ask questions on how to operate something in the program not hack or mod it.
PhotoPost just like vbulletin does not support or assist with code hacking. I try and help you guys out the best I can but I really do not appreciate semi flip remarks as in that is why I am here in the how do I forum as that usually will get someone the stock answer like over at
vb. Go discuss mods outside support.

I know you know the rules I know I have explained this before.
Your comment kind of sounds like I am suppose to know exactly what your doing which of course I do not. I am not the one hacking the code. I gave you a link that works in one place thats it here. I merely said you would need to use the correct variable where ever you decide to hack things.
If your trying to put a link in the postline then you would need to do so in the actual postline where it is formed in the vb3.php integration file under the forums subdirectory and use the variable $cuserid. That is the last hint I will give here.
