Is it possible to stop registered users from being able to post pictures

[ziggy2004]

we are having spam problems with spammers who post offensive pictures. As we are a parenting forum and users will often view posts with young children around we really want to find a way to stop the pictures appearing.

What we want to do is change the settings of the registered users usergroup to stop registered users posting pictures. Then we want to do an automatic upgrade to a new usergroup for users with at least 5 posts who then can post pictures. We have a usergroup with an automatic upgrade already so that is not the problem the problem is that we cannot find how to change the settings so that pictures cannot be posted. Does anyone know how to do this?

Many thanks

Yes, you can disable the IMG bbcode tag (I've done this on mine) to stop people linking to images. Unfortunately you can only do this per forum, not per usergroup.

You could also disable image attachments, which can be done per usergroup, to stop problem uploads.

The main reason I did this was to stop huge linked images breaking my forum, so I disabled the IMG bbcode to stop this (users instead upload images using the attachments option). You could also do that but go one step further and disable attachments too for the base usergroup, between the two settings it will prevent problem images. Make sure you also stop signature images, avatars and profile pictures for that user group.

As Ingenious wrote, the img bbcode cannot be controlled per usergroup in posts. So, the only solution I see, is to add 2 plugins, one for the "newpost_process" hook (new posts) and the other
for the "editpost_update_process" hook (updated posts). The code in both plugins, can be common:

/**
 *  init
 */

$z_is_post = is_array($post);
$z_message = $z_is_post ? $post['message'] : $edit['message'];

/**
 *  run
 */

if ($vbulletin->userinfo['usergroupid'] < 5)
{
    $z_message = preg_replace('~\[img\](.+)\[/img\]~iU', 'no images, please..', $z_message);
}

/**
 *  done
 */

if ($z_is_post)
{
    $post['message'] = $z_message;

    $dataman->setr('pagetext',$post['message']);
}
else
{
    $edit['message'] = $z_message;
} 

Feel free to change the condition+action in the "run" section to better suit your needs. For example, change 'no images, please..' to '\1' to show the url, etc

You can also check that mod. Yes, its a 3.7 one, but it works fine on my 3.8.4 build. It adds something down the bottom of the forum settings that you can select the number of posts that the user must have before they can see images, post images, post links, etc - brilliant mod.

Good link - this is one of the key strengths about vB, the number of really useful mods out there.
