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.

Do you have any kind of compression running? maybe mod_gz or some other kind of webserver output compressing?

Hello
Thanks for your reply.
Does any kink of the compression influence on your mode?
I am not sure if I have any of those compression. Could you please tell me how to check if any of the running on my server ?

where can i get it for vb 4.1.5

Hello,

I have a question. I have been using this mod since the first day it was released, and is wonderful.

But recently i have changed my CMS thumbnail preview image size, from 175 to 350, and i clear all the caches, and generate the thumbnails (attachment images) again, and the same with this mod cache.

And now the issue is that the images are correctly watermarked, but the new 350px thumbnail aren't. Before i could see the watermark in the thumbnails too.

Can you give me any idea to solve this? I would like to have myy new bigger thumbnails watermarked too.

Vb 4.1.7.

in the mod settings I have minimum image size 150 (before with the thumbnails 175 it worked perfectly).

Thanks!

hmm this is strange... When you change the size back to where it was before, does it work?

Disasterpiece,
Are we supposed to get instructions on watermark removal after making a donation? I've manually removed mine, but I wouldn't mind some official instructions to make sure that I've done it right.

I'm also still having problems with older photos not being watermarked. Is this expected behavior (only photos uploaded recently get watermarked).

You can send me your server credentials per PM so I can take a look myself.
preferably ftp/administrative forum account.

Sorry, I have thousands of attachments, is it necesary to recalculate all again? I will PM you with my forum info, so you can see the problem,

If it's necessary to recalculate i will do,m but I would like not to recalculating/generating all again (a lot of time and page slowing down,...)

Thanks!
