Attached Image Watermarking PLUS Guest Viewing of Thumbnails
Developer Last Online: Mar 2012
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:
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']; 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 $vbulletin->userinfo['userid'] == 0))) Code:
if (!($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']); 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) - $startbyte)); Code:
// ######################################### // ##### Start modified section for watermarks // ##### Changed to prevent filesize header on watermarked images // ######################################### if (!defined('WATERMARKED')) { header('Content-Length: ' . (($lastbyte + 1) - $startbyte)); } // ######################################### // ##### End modified section for watermarks // ######################################### ============================================= STEP 6: Find this line of code: Code:
($hook = vBulletinHook::fetch_hook('attachment_display')) ? eval($hook) : false; Code:
// ######################################### // ##### Start modified section for watermarks // ######################################### if (!$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; 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. Show Your Support

Works with 3.8.1 but you have to turn off Lightbox. Would really like for it work with Lightbox, any chance of that happening?

followed directions exactly. It works every now and then on 3.8.2 but sometimes says error on page and when you click the attachment it only shows a big black empty transparent box.

HOLY smokes... I really need a watermarker (just text) but the process for this mode is just WAAAY to long.
Does anyone know of a simple upload-subdirectory-import-xml type mod for placing simple text on say the bottom right of every uploaded image? |

Copy and paste a few lines and its done. How much easier do you want?
I just installed it in less than 15 minutes and that was while staying on top of my normal job. Great Mod btw, I wanted something that would not only watermark new images but also existing (a couple gigs worth). This is exactly what I was looking for. Thank you!! |

Actually I just installed this one, very quick (no editing required):
https://vborg.vbsupport.ru/showthread.php?t=201972 EDIT ^^ the above watermark add-on is EASY to install *BUT* - it stops your "Times Viewed" counter from working (when you hover over thumbnails). I may just try the add-on in this thread now. Except I have a 'guests can view thumbnails' add-on already and am scared that this mod will clash with it and mess the settings up since this one has the same feature. |

Hello, Does this mod works on 3.8.3 version? Also, Could anyone try to add a check/un-check option on Manage Attachments window where the user can select whether to watermark the specific image(s) or not.
