Hello.
If you want to add image verification for 'REGISTERED' users, one method is to do the following:
in "sendmessage.php", search for 'imagecheck'. You'll find this word exists in 2 places.
For each instance, in its associated block of code, modify the following line:
FROM:
====
PHP Code:
if (!$vbulletin->userinfo['userid'] AND $vbulletin->options['contactustype'] == 2 AND $vbulletin->options['gdversion'])
TO:
==
PHP Code:
if (!$vbulletin->userinfo['userid'] OR $vbulletin->userinfo['userid'] AND $vbulletin->options['contactustype'] == 2 AND $vbulletin->options['gdversion'])
Hope this helps.
