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.

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.

I'm using 4.2.0 and I am not seeing any watermark on the pictures even after refreshing and my images in the vault wiki aren't showing at all.

I'm using 4.2.0, and I managed to get this addon working. Two things that I did that weren't completely obvious:

1. moved the images OUT of the DB into the file system.
2. added the GD module to the web server.

It works now, BUT I've got performance issues. The first view of a photo usually shows the spinning icon indefinitely and you must click the icon to see the full sized image to get past the place it gets "stuck".



I'd much rather the extension made the watermarked images for the cache at the time they were uploaded and not when they are first viewed.


Otherwise, it works brilliantly.


If I was going to BEG for an additional feature, it would be an option for users to add their own individual watermarks as well.


Thanks for this Disaster!

Hi , the watermark image would not show because I had another name for the admin directory. Once I renamed Admincp, it worked. Anyone know a workaround, because I like having a different name for the admincp.

This should be a given for all vbulletin customers. I'm surprised the creator of the plugin hasn't used the variable instead of hard coding it

This means I'm probably not going to be able to use it either now...

no issues with 4.2.0 PL2. all attachments are watermarked.

had images in database and it worked. recently moved to file system and they work as well.
changed servers, imported 3 vB sites into one (impex) and all old attachments got the watermark as well.

I just tested this with PHP 5.3 and it was breaking the watermark and attachments came out in halves. i switched back to 5.2 and all is good. attachments upload fine, displayed inline fine with watermark

[snotek]

I seem to get these randomly and I can only surmise that it happens everytime an image is uploaded to the site. (which would naturally be watermarked per your add-on)

Database error in vBulletin 4.2.0:

Invalid SQL:

REPLACE INTO datastore
(title, data, unserialize)
VALUES
('plwm_cache', 'a:1:{i:0;s:2:\"87\";}', 0);

MySQL Error : MySQL server has gone away
Error Number : 2006

Error Date : Sunday, September 2nd 2012 @ 09:56:40 AM

The issue that I have is that it's always generated by an "Unregistered" user, which on our site has no permissions to post, thus no permissions to upload images. The IP address listed is also always from some foreign country. (.fr in the example above)

My biggest fear here is that this script can be used to compromise the security of our server and that is no good.

Can you please explain why these errors occur and how they may be corrected?

Hi

Not related with the mod, appears when the mysql server is stretched beyond its performance limits.

@Disasterpiece

I know you do not support this mod, but I have a question I hope you would answer.

I have installed DBTech Dragonbyte Gallery (link) and your mod doesn't seem to work with it like it does using Picture and Gallery (link). Is there something I'm over looking or the two mods incompatible with each other?

Thanks in advance.

No, the mod does only apply watermarks on images which are hosted on the same server.
