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.

Hi, I was wondering if I install this add on, will photos still be watermarked if people right click on the pictures and and save it?

Respectfully,
KP

Running 4.1.6.

I'm getting "Cache Path Doesn't Exist!". I'm not sure what you're looking for here. I've tried /cache/ I've tried /websiteurl/cache/. I've tried everything I can think of, but nothing seems to work. My cache path is set to 777.

Images path says the same thing, yet it's showing my image in the Watermark Preview thingy.

This has stopped all images from working now.

What's up with my settings, or your mod?

I'm not getting a preview at the bottom either.

This is when I look at the preview image URL.

But you do know how paths work in unix systems?

/cache/ means the absolute path. It would look for a directory named "cache" in the root dir /
I think you meant relative paths from the current web directory the script is located in. then you need to remove the first slash: "cache/"

or to be sure, use the full absolute path. Let's say your web directory is located in "/var/www/vhosts/somedomain/htdocs/"
then you want to use the following path:
"/var/www/vhosts/somedomain/htdocs/cache/"

This indicates, that you didin't upload the sample image file which should go to your forum's image directory with the filename "watermark.png"

Check the archive you downloaded here and upload all files, including those in the image dir branch.

Meh...appears more full of fail than anything. It either works or it doesnt....and it doesnt. Images dont show...no water marks....cache exists....but your program continues to say it doesnt. Being I have wasted about two hours on this at this point....I'm out.

Appreciate your efforts and work ....

Any updates on this problem?

Currently have mod turned OFF, so I was wondering if there's been any progress to determining why this seems to be a hit and miss problem...

Thanks ..

I couldn't reproduce this problem on 3 different web server configurations yet.

And tbh this mod isn't the focus of my attention right now, so it'll take some more time or perhaps another skilled fella who'd like to take a look at this.

[laktrui]
