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.

Actually it doesn't really matter if you store the files in db or filesystem. For the mod it's much faster to use the filesystem, so it can perform a fast check if the file is already cached than having to query the database for each case.

I recommend to store the attachment in the filesystem, otherwise you would carry the whole attachments in each of your database backup where the cached watermark files are on the filesystem nontheless.

Thanks, I will transfer them from Db to filesystem.

Great mod!!!

I recommend it, and great support!!!!!!!

It doesn´t work on my 4.1.8. The preview is ok, but not when I applied it. Then you can´t see the pictures , just an X instead.

Now it works. I forgot the TMP and 777.

Yep, that's necessary to make the watermark processing work

Hi and thank you for this mod!

Is it normal that the watermark is applied only to the full image and not to the thumbnail?
Also I had to disable the lightbox popup, 'cause it makes this problem: https://vborg.vbsupport.ru/showpost....6&postcount=35

[fromtheflames]

This helps sorting out how to process the thumbnail, but a coded by the author solution is appreciate!

[Disasterpiece]

Yeah, well it didn't make much sense to me to include thumbnails as well, because.. they're just low quality previews. Who wants to steal them? :P
Also it takes up additional cache size for no reason in my opinion, but I'll include an option there as well.

[fromtheflames]

my thumbs are 500px wide (other admin wants so), so I think others could steal it.

thank you!
