[hollabizzack]

help i'm trying to install the vbhome lite v42..but i do not understand step #4,here is what it says...........

Open vBulletin Admin Control Panel and a new {imageshome} replacement variable to your full website URL, like that:
Replacements > Add

and enter the following information:REPLACEMENT SET
(your choice here)
CODE TO FIND
{imageshome}
CODE TO INSERT
forum/images

Change the code to insert to match your forum location. Save the replacement variable.

im using vb3.
so my question is where would {imageshome} be located in the admin control panel?
