OK.
This one's for hardcore PHP programmers (namely nuke_phpbb forums).
I want to do something similar to what happens here with Esato's hosted images. This is, and unlogged (anonymous user) can't view the pic in a post, and instead, another pic is placed.

So i need to parse a $message and replace any URL in <img> tags and between [img][/img] BBcode tags (don't really know if both aplly).

I'm completely lost here...
Maybe laffen could give me a snip of his code...

I'm very thankful to anyone who can point me a direction.

Cheers.

Statndard PHP stuff like search and replace using 'ereg' bits should do what you want .

I tried something like the "ereg" thing. Namely "preg_replace" but i failed to get it working.

A code snip would be very much appreciated.

OK. I got it.

Just before the "Parse smilies" section in viewtopic.php

put this:

////////////////////////////////////////////////////////////////////////
// TWEAK TO REMOVE IMAGE DISPLAY FROM NOT LOGGED IN USERS
//
// PG: 2005/04/13
////////////////////////////////////////////////////////////////////////
if (!$userdata['session_logged_in'])
{
$message = ereg_replace("<img[^>]*>", "<img src="modules/Forums/images/logintoview.jpg">", $message);
}


And voilá!
