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.

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.

I have this same problem, I read the answer No. 96 hayo but not the solution.
other than that to write images remain in miniature and I can not see them in large or Siqueira copying the link of the image in the IMG tag .. I'm so lost, not to do.

I hope you can help me, thanks.

It is important that your cache directory works.

If you're running on a linux machine, then the most common value would be "/tmp" (without quites)
Try that and report back if this counts as a valid cache directory.
If you have success, the images should appear as well.

Oh it works perfectly Thank you very much mate, I was really going crazy looking for the solution and place the link was just good in the cache

That I make when loading an image, it comes in real size. No thumbnails?

Thanks...

[oddmud]

Finally got it to work, thanks for the better explanation.

Now my forum is running really slow, is it back dating all the old photos and adding the watermark? Or does it do it on each call up of the image?

[Disasterpiece]

It does only add watermark when the image is not in the cache, a so called "lazy" method.
Check the overall cache size, I don't think that the watermark tool is causing the problem tho

[WDS]

Disasterpiece

I've been looking but not how:

I want to upload an image that aparesca with and without miniature size.
Ie I raise the image and automatically display actual size.
and disable the thumbnail at the end of the post, is very ugly.

Thanks.

Is this compatible with the vb option:

"Save Attachments as Files" YES?

Or attachments have to be stored in the DB for this mod to work?

I ask, because I have been looking for server optimization (Vb optimise 2.0.1 mod), and this is one of the things recommended to do, to save attachments as files instead the default DB storage of Vb.

Please any help would be apreciated,

Thanks!

[Disasterpiece]

the mod works with both files being stored on the filesystem and the database.

Keep in mind tho, that the cached watermark files are stored in the filesystem, regardless of the vbulletin options.

This means: Your original files without the watermarks are stored as you define it in the vB settings db/disk but the watermark mod stores the cached files only in the filesystem.

[inigo]

Thanks for your fast response.

So, in this case, using your mod, is the same the vb storage option:

DB or filesystem

because the images would be cached with watermark in files and served directly, isn't it?

Or in spite of this watermarked files cached, would be better to storage the original images in files instead the DB?

Thanks very much!!!!!
