Disabling images for guests

Hi all,

I have been searching through the scripts "forum_posts.asp" and "functions_format_post.asp" for a particular piece of code but I have yet to have any luck. I am trying to disable the display of any images, links, files etc. to non-registered users and guests. I have found the "FormatForumCodes" function but any changes I make fail to show when a thread is generated via "forum_posts.asp". Am I editing the wrong files or is there a obscurely named function which I have unable to locate in the above files?

Any help is really appreciated as this has been bugging me for days!

Cheers.
