Social Group and Album Enhancements - Watermark Generator

Quick Info

This mod adds a watermark to album and attachment images.
The watermark is customizable via image files or specified text.
Processed images are cached and the original files remain untouched, so you can modify or remove the watermark anytime you want.


Features

- Intelligent Caching
- Uses standard vBulletin methods, therefore no file modifications necessary
- Settings-Preview with a sample image in Adminpanel
- Generative plugin behaviour, works with most other mods which use the same hooks or use attachment images elsewhere

Installation

Step 1)

Upload files inside upload directory according to their structure:

> forum root
	> admincp
		+ pl_watermark_admin.php
	> images
		> misc
			+ plwm_sample.jpg
	> includes
		> cron
			+ pl_watermark_cron.php
		> xml
			+ cpnav_plwatermark.xml
		+ pl_watermark_functions.php
		+ pl_watermark_imagemanipulation.php


Step 2)

Import "product-plwatermark.xml" as addon into your vBulletin AdminCP


Step 3)

Navigate in your vBulletin AdminCP to PL Watermark Generator -> Plugin Settings.
Define the settings how you see fit. The options should be self-explanatory, if you need help with certain things, ask in the modification thread.

Changelog

Additional Info

The Mod is currently in BETA. This means, that we tested it on a test environment (vb 4.0.x to 4.1.3) but has not yet undergo excessive stress test.
Keep an eye out for updated versions until the final release!
If you encounter any bugs, missing or misplaced features, let us know!

F.A.Q

- I don't see changes in my live images!
> To see changes on the image files you have to clear your browser's cache!
In firefox it's enough to force a fresh reload via STRG+F5 and on other browsers STRG+F5 or SHIFT+F5 should work.
If you don't perform this step, your browser will show the old cached version and maybe the watermark won't show or changes won't apply.

- My png/gif watermark isn't transparent, instead I get a black background!
> PNG-8 is known for having transparency problems, GIF in some cases as well.
Fall back to PNG-24 with Alpha channel (all modern image tools should be able to save as PNG-24)
If you have trouble creating a working png-24 with alpha channel, you can send me a PM with a link to your watermark and I'll convert it to png-24 for you.

- I have trouble with special characters or non-latin charactersets!
> The addon is using standard php functionalities for the text. If for any reason you have trouble with special chars, I suggest using a transparent png-24 with the text from an external image tool instead.

Yes and how!? Don't understand it at all i have run those test files from 1 to 100 and now the images are showing most of them even in the cms! But a lot of old ones don't! (looks like they don't even exist!) So will remove them by time.

So for now i'm very happy because now on all new images it will show and it works! Using vB4.2.0 PL3

THANKS

Is there a possibily to let this mod work with this: Import external images ?

Did your server configuratio change? There are two major image tools available for linux, which are GD(2) and Imagemagick. One of them both works, the other doesn't with the mod. You can find it in the vbulletin settings somewhere in the category General or Graphics or Server Settings. Which one do you use?

Hello. I've got the same problem here. It persists because server is sending "Content-length" header with the real attachment size (not the watermarked one). I've tried to modify the product's plugin to fix this, but nothing happens, becase this header is sended before the hook called.
So, I just commented the "Content-length" header string in attachment.php:

header('Content-Length: ' . (($lastbyte + 1) - $startbyte));

And now it's works, but I think author should fix this problem in his product. Thx. = )

This mod is not supported and last update was about 19 months ago. I wouldn't look for an update, but your post is valuable to others with the same problem.

I have the same issue on my 4.1.11 forum. The mod has been working great for months, and the watermark shows on all newly uploaded photos, but doesn't show on photos uploaded before the mod was installed.

It doesn't matter the type of image (png / jpg, etc). I can take an image that isn't showing a watermark, save it locally then reattach it and the watermark will show.

I love this mod and will continue to use it - I just wish I could get all my photos watermarked.

[dizzynation]

This would be a great mod for my forum. What are the chances of it working on 4.2?

Also is there an option to set certain opacity % for the watermark?

TerryMason - Have you tried running the General Update tool?

[fxdigi-cash]

I haven't tried this mod myself yet, but willing to give it a shot....

on the other hand, I tried this mod on my vb.4.2 pl3 : https://vborg.vbsupport.ru/showthread.php?p=2398684

I know it is for vb3.x but surprisingly works on vb4.2 pl3

cheers

I tried this but it just broke all my attachments.

Can somebody share the correct way to comment out this line?

Edit - Alibass showed me this (MUCH APPRECIATED!!)

/ header('Content-Length: ' . (($lastbyte + 1) - $startbyte));

if that doesn't work then try this

<!-- header('Content-Length: ' . (($lastbyte + 1) - $startbyte)); -->

I also tested this watermarker also -
https://vborg.vbsupport.ru/showthread.php?p=2398684

And it works great, just an XML file with one minor edit, I'm using VB 4 PL3 if anyone finds this one doesn't work.
