// $Id$
// General purpose image bbcode. As well as the obvious insertion of a picture:
// a) if filname begins with 'th_' or 'thumb_', creates link to main image opening in new window
// b) If filename contains '*', treats it as a wildcard, and displays a random image from all matching file names found
//
// Can use simple classes for float - e.g.:
// .floatleft {clear: right; float: left; margin: 0px 5px 5px 0px; padding:2px; border: 0px;}
// .floatright {clear: left; float: right; margin: 0px 0px 0px 5px; padding:2px; border: 0px;}
// Currently defaults class to 'floatnone' - overridden by bbcode
if (trim($code_text) == "") return ""; // Do nothing on empty file
if (preg_match("#\.php\?.*#",$code_text)){return "";}
