Thanks Satan, always needed one of these!

The only way to ensure it is to either have them upload them as attachments, or check it on every page-load :ermm:

Well if it is done during the posting process, say when the new post information is added to the database, if it checks it then - placing [url]path[*/url] if the image is too large and [img]path[*/img] if it is within the limits - even if they changed the file on the remote server, the post would still have the url tags in it. Then you could just repeat the same process for edit post should they try and get past it that way.

:ermm:

Yet, once again, I was responding to the wrong thread. :rolleyes:

Anyways, thanks for the update. I'm sure the whole world could use this.

Now here's the real sollutions... To everything:
  • 1. You configure it to only allow images from a specific directory on your server, like:
    • A) Your vBadvanced gallery.
    • B) Or someone makes the long anticipated user upload signature pic hack.
    • C) FTP

I don't know how reasonable this is, but one way or another, the idea is to stop the user from updating his signature on the server end. Am I right? Because after his sig is set, he can go to photobucket and replace his mymugshot.jpg with a bigger mymugshot.jpg
  • 2. Limit the # of images.
    • (1) is safe number. Anything else and you're asking for it.

that is all. :)

If you have upgraded from vB 3.0.x it appears that the Name of the Error Messages is not reset from "Front-end Error Messages" that was used in vB3.0.x to "Error Messages" that is used in 3.5 :)

They are both the same thing though :)

Much love to KirbyDE for helping me out with my request.. :D

This is the resulting plugin:
Code:
if ($vbulletin->options['allowsignatures'])
{
        $maxsigwidth = 400;
        $maxsigheight = 150;

        function check_sig_size($sig)
        {
                global $maxsigwidth, $maxsigheight, $errors, $vbulletin;
                $sig = str_replace(array('  ', '\\"'), array('', '"'), $sig);

                // check valid signature image size
                if ($imginfo = getimagesize($sig))
                {
                        if ($imginfo[0] > $maxsigwidth or $imginfo[1] > $maxsigheight)
                        {
                                $vbulletin->GPC['preview'] = 'true';
                                $errors[] = fetch_error('signaturetoobig', $maxsigwidth, $maxsigheight);
                        }
                }
        }

        $url = preg_replace('#\[img\]\s*(https?://([^<>*"' . iif(!$vbulletin->options['allowdynimg'], '?&') . ']+|[a-z0-9/\\._\- !]+))\[/img\]#iUe', "check_sig_size('\\1')", $signature);
}
The phrase then becomes something similar to:
Quote:
Your signature can not have images larger than {1}w x {2}h in pixels.

Is that the entire hack in this xml then?

Yes, you can install the plugin via hellsatan's .xml file and then replace the code with the above.
