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.

Is it possibe to also watermark the INLINE pictures added to a post?

As far as i can see, only the attached pictures are watermarked.
I have now disabled inline attachements on my forum.

Your test image was ok, but with no trasparency.

So the problem is solved, PNG-24 working, but I have to do more tests, because there are some of the images without watermark,... and I think is because the browser's cache.

so I will tell you when I can test deeply,

Thanks,

Yes, PNG-8 seems to be a problem right now, I'll look into it.
Sadly, the php functions for image prcessing are limited, so its hard to find advanced tools without relying on external libaries not everyone has.

For now, PNG-24 should work with full transparency, so I recommend to use it, also for the case if you run into charset issues with non-latin characters.

I was sure that the inline post uses the same attachment method. Which inline-images do you mean?
Those where people simply attach an image, grab the url to the fullsize picture and add that to the post?
Or do you mean linking images from 3rd party sites?

How this affects images that user chooses as background image for his profile?

That is a good question, didn't think of that. I'll check it out and update if necessary.

Well, they're external links, which means these images aren't hosted on your server. So there is no need to (and in fact, you shouldn't) add a watermark to it, because they aren't "yours".

[Stefan118]

Ok, i thought it was becouse the member has put the image between the post, instead of an attachment.

But indeed, after i have read your last post i figured out they are indeed external.

Thanks for clearing that out !
