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.

Working fine here on 4.2.0

Is there a way to exclude image types that are watermarked?
We have a resident photochop/gif funny guy and its watermarking his GIFs. The images are flattened and it only shows a gray box.

I'd like to exclude the filetype GIF from the watermark process.

Other that that, 4.2 PL2 and its working great.

How should the program know when a watermark already exists?

Installed on VB 4.20 seems to be working straight out of the box for me. Many thanks!

I especially appreciate the min. image size to apply to feature.

Sorry, I guess I wasn't very clear. It has nothing to do with existing watermarks.

I just want to exclude any file with a .GIF extension from being watermarked.

I've heard of this problem but have not encountered it myself so far. I suspect some kind of output compression to be the problem since it modifies the file size and then the header file size field doesn't match anymore. Do you have any kind of gz compression active on your server or your forum?

Installed it and it it not working for me right now! I run your testattachments.php and it gives me this awnser:incorrect id!

Some thumbs are showing others don't and all the big images are not working also.

I had this mod installed before on an old installation and then it's working fine installed it on new installation and it's not working. Can it have to do i imported my things with impex?

Thanks,
Patrick
