No support by the author.

I had been looking for these two options for quite a while, and was finally able to hire Brian (of vBadvanced) to write them for me. Since a lot of people have been looking for this, I have decided (with Brian's permission) to release this as a free, unsupported, modification.

This modification will allow you to specify a watermark image that will be overlayed over any attached JPG or PNG file on your site in real time, as the image is displayed. NO PERMANENT CHANGES ARE MADE TO ANY OF YOUR ATTACHMENTS. You can also exclude specific forums and usergroups from seeing the watermark.

As an added bonus, he included the ability to allow guests to see attached image thumbnails, while still requiring them to register to see the full size attachments. (Make sure you have your Unregistered / Not Logged In usergroup set to NOT have access to download attachments.)

PLEASE CLICK INSTALL so that maybe Jelsoft will include these as built-in features in a future version.

Notes/Troubleshooting:
  • Your server needs to have GD2 installed.
  • Attachments must be stored in the file system. Database storage of file attachments will not work.
  • Make sure you use the full PHYSICAL path to your watermark image.
  • Make sure you have a low number in the width/height setting. (I use 200, since my watermark image is 150 pixels wide.)
  • If you have previously viewed the attached image, your browser may cache it, so you will need to clear your browser cache or force a hard refresh (CTRL-F5) while viewing the image to get the new watermarked version.


Well, on to the modification:

=============================================
STEP 1:
Since the resulting file contains too much vBulletin code, I am unable to include it with this modification. So, the first step is to copy vBulletin's attachment.php to a file named attachment_watermark.php. Then, edit attachment_watermark.php, making the following changes.

=============================================
STEP 2:
You need to delete a LOT of lines from the top of the file. Find this line...
Code:
$idname = $vbphrase['attachment'];
...and delete everything ABOVE it other than the <?php line at the top of the file.

Your attachment_watermark.php file should begin with this code when you've completed this step:
Code:
<?php
$idname = $vbphrase['attachment'];

=============================================
STEP 3:
Find this line of code:
Code:
if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['cangetattachment']) OR (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewothers']) AND ($attachmentinfo['postuserid'] != $vbulletin->userinfo['userid'] OR $vbulletin->userinfo['userid'] == 0)))
REPLACE with this code:
Code:
if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']) OR (!($forumperms & $vbulletin->bf_ugp_forumpermissions['cangetattachment']) AND !$vbulletin->GPC['thumb'])  OR (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewothers']) AND ($attachmentinfo['postuserid'] != $vbulletin->userinfo['userid'] OR $vbulletin->userinfo['userid'] == 0)))

=============================================
STEP 4:
Find these lines of code:
Code:
	else
	{
		$attachpath = fetch_attachment_path($attachmentinfo['userid'], $attachmentinfo['attachmentid']);
Add this code BELOW the lines referenced above:
Code:
// #########################################
// ##### Start modified section for watermarks
// #########################################

$vbulletin->options['attach_water_exforums'] = explode(',', $vbulletin->options['attach_water_exforums']);
$vbulletin->options['attach_water_exgroups'] = explode(',', $vbulletin->options['attach_water_exgroups']);


if ($vbulletin->options['attach_water_filelocation']
	AND in_array($extension, array('jpg', 'jpeg', 'png'))
	AND !in_array($attachmentinfo['forumid'], $vbulletin->options['attach_water_exforums'])
	AND !array_intersect(fetch_membergroupids_array($vbulletin->userinfo), $vbulletin->options['attach_water_exgroups'])
)
{
	$attachsize = getimagesize($attachpath);

	if ($attachsize[0] >= $vbulletin->options['attach_water_minsize'] AND $attachsize[1] >= $vbulletin->options['attach_water_minsize'])
	{
		$waterimage =& $vbulletin->options['attach_water_filelocation'];
		$watersize = getimagesize($waterimage);

		$waterext = strtolower(substr($waterimage, strrpos($waterimage, '.') + 1));

		// Coordinates (height)
		switch ($vbulletin->options['attach_water_coordinates'][0])
		{
			case 'n':
				$waterpos['height'] = 0 + $vbulletin->options['attach_water_padding'];
			break;
			case 'm':
				$waterpos['height'] = round(($attachsize[1] - $watersize[1]) / 2);
			break;
			case 's':
				$waterpos['height'] = round(($attachsize[1] - $watersize[1])) - $vbulletin->options['attach_water_padding'];
			break;
		}

		// Coordinates (width)
		switch ($vbulletin->options['attach_water_coordinates'][1])
		{
			case 'w':
				$waterpos['width'] = 0 + $vbulletin->options['attach_water_padding'];
			break;
			case 'c':
				$waterpos['width'] = round(($attachsize[0] - $watersize[0]) / 2);
			break;
			case 'e':
				$waterpos['width'] = round(($attachsize[0] - $watersize[0])) - $vbulletin->options['attach_water_padding'];
			break;
		}

		// Watermark ext
		switch ($waterext)
		{
			case 'jpg':
			case 'jpeg':
				$watermark = imagecreatefromjpeg($waterimage);
			break;

			case 'png':
				$watermark = imagecreatefrompng($waterimage);
			break;
		}

		// Attachment ext
		switch ($extension)
		{
			case 'jpg':
			case 'jpeg':
				$attachimage = imagecreatefromjpeg($attachpath);
			break;

			case 'png':
				$attachimage = imagecreatefrompng($attachpath);
			break;
		}

		imagealphablending($attachimage, true);

		$watermark_width = imagesx($watermark);
		$watermark_height = imagesy($watermark);

		imagecopy($attachimage, $watermark, $waterpos['width'], $waterpos['height'], 0, 0, $watersize[0], $watersize[1]);
		define('WATERMARKED', true);
	}
}
// #########################################
// ##### End modified section for watermarks
// #########################################

=============================================
STEP 5:
Find this line of code:
Code:
header('Content-Length: ' . (($lastbyte + 1) - $startbyte));
REPLACE with this code:
Code:
// #########################################
// ##### Start modified section for watermarks
// ##### Changed to prevent filesize header on watermarked images
// #########################################
if (!defined('WATERMARKED'))
{
	header('Content-Length: ' . (($lastbyte + 1) - $startbyte));
}
// #########################################
// ##### End modified section for watermarks
// #########################################

=============================================
STEP 6:
Find this line of code:
Code:
($hook = vBulletinHook::fetch_hook('attachment_display')) ? eval($hook) : false;
REPLACE with this code:
Code:
// #########################################
// ##### Start modified section for watermarks
// #########################################
if (!$vbulletin->GPC['thumb'] AND defined('WATERMARKED'))
{
	imagejpeg($attachimage);
	imagedestroy($attachimage);
	imagedestroy($watermark);
}
// #########################################
// ##### End modified section for watermarks
=============================================
STEP 7:
Find this line of code:
Code:
($hook = vBulletinHook::fetch_hook('attachment_complete')) ? eval($hook) : false;
REPLACE with this code:
Code:
exit;

=============================================
STEP 8:
Save and upload attachment_watermark.php to your forum root directory.


=============================================
STEP 9:
Install the product-attach_watermark.xml Product via the vBulletin AdminCP Product Manager.


=============================================
STEP 10:
Configure the options at AdminCP -> vBulletin Options -> Attachment Watermarks. All fields should be self-explanatory.

Sorry. A lame question. If a member downloads an image to his PC, will it carry the watermark or will the watermark work inside the forum only?

It will if you set it low enough but watermarking thumbs is not necessary imo.

The reason I asked about the thumbnails is I have a friend who is looking for a hack that does image watermarking on thumbnails. But they are not always the same size. How hard would this be to adapt for thumbnails of different sizes?

If you right click and save image the image will have the watermark. I don't think the original image is watermarked when you allow a actual download of the image.
Programs like PhotoPost allow watermarking of the the original image on the upload and on the fly.

Your problem would be the watermark. If it is small enough to mark a thumb you wouldn't see it on a large image.

i finally got mine working and looks great.

As for if the watermark is bigger, that depends on what ur watermark is if it will look stupid

The watermark is overlayed over the the image and the image stays the sizes of the original image, not increasing to the size of the watermark which was the question i was kinda getting at.
