AND make sure that the file (in code 'image.gif') DOES NOT exist. You can test against: http://economads.com/libaware/_font/title/image.gif This crashes on my server - running PHP 4.3.0 as CGI with IIS Win2000. Hope this helps. ------------------------------------------------------------------------ [2003-01-20 17:13:18] sniper@php.net Ahha..so you had propably the old php4ts.dll there, from previous version... ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
