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 tried this mod on my vb.4.2 pl3 and don't work, dont load the images
Uninstalled.....

[grafixonline]

I also installed it on my vb 4.2 and the images would not load. Is there a fix?

[Disasterpiece]

Try changing the image plugin. GD or imagemagick, one should work, the other won't.

[MZF-Onkel]

Works mostly fine under vBulletin 4.2.0 Patch Level 3.

In some old images, the watermark will not be shown, but in all newly uploaded it works

We use GD, here are some more informations:

GD Support enabled
GD Version bundled (2.0.34 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.2.1
GIF Read Support enabled
GIF Create Support enabled
JPEG Support enabled
libJPEG Version 6b
PNG Support enabled
libPNG Version 1.2.10
WBMP Support enabled
XPM Support enabled
libXpm Version 30411
XBM Support enabled

It's in my opinion the BEST MOD for using Watermark in Images.

Best regards
Onkel

Dear Onkel,

When u install it, the watermark works for u in admin panel preview section ???

I my case I see the watermark, and I can test with the text option of watermark, but If I try use watermark image dont do nothing.

Best Regards

[MZF-Onkel]

we tested it with the TEST Image, this works fine.

In the beginning we have some problems with the Images, they don't loaded.

I've installed an actually GD Version on the Server an now it works fine.

The problem that some old pictures have no watermark persists, unfortunately.
I don't know why.

Have you check your cache directory?
Have you installed some other Mods?

Best regards from Berlin

[Disasterpiece]

I have no solution for the missing watermarks on older images, but can you use a different browser and checks if its still the same? Maybe your browser just cached old images.

Or try to move your attachments between database and filesystem once so they get reprocessed. Maybe it starts working then.

I am yet another user of this mod who would appreciate the option to stop it from watermarking images attached to posts in certain forums. Please consider this feature for the next release!

Also please consider moving the admin cp options to the standard position along with all the other VB plugin options, under the normal settings link. It seems unnecessary for this to have its own seperate menu.

This is already on the to-do list for the next update.

The usual settings page is not as flexible as a custom admin menu, but I'll see what I can do to put it all in one place.

The only issue i have with this SUPER mod is that it doesn't clear the cache after X seconds?
or is it minutes or days?

I hope it is seconds, just as about everything in vB.
If not, please do not laugh

I have set it to 86400 seconds, that should be 24 hours...
The cache is now 5 days old since i manualy cleared it.
