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.

For example, it seemed to be working fine on recent uploads, then a member just added 3 pics that are 1279px ? 959px, they display fine, however, all three have a grey bar across the bottom.

I noticed that another member immediately afterwards uploaded some pic attachments that were less than 1024x768 and the watermarks show just fine on them ...

Hope that helps debug things ... :up:

Doug

Edit: I've added another example that shows how large pics seem to a factor in triggering the grey bar. The pic attached is one a member just uploaded as an attachment and it's 2448px ? 2958px (scaled by vBulletin for internal storage to 532px ? 643px).

I'm having the same problem. Is there any solution yet?
Happens when you you upload bigger pics and when the watermark is not set to the bottom. When I set it to the bottom corner, it's working fine. But I want to get this working with the watermark in the center.
Using vb 4.1.9

The scheduled task for cache pruning does not work for me.

Cache liftime is set to 86400 (1 day) and lru table size is set to 100.
The task is scheduled at 9 am.
I'm running vbulletin 4.1.11

When I look into the cache dir I find all the files created since the last manual cache prune, while I suppose only to see files created from 9 am of yesterday, and no more than 100 files.

[Mopar1973Man]

Really good mod! :up:

I got it installed on 4.1.11 and no problems so far... I really do like the different options, preview panel, etc.

Dear Disasterpiece,

installed your Add-On on my forums (4.1.11) and everything seemed to work as we have tested the Board; but now in Live-Stages just two questions

1) MySQL-Errors

Invalid SQL:

			REPLACE INTO datastore
				(title, data, unserialize)
			VALUES
				('plwm_cache', 'a:1:{i:0;s:3:\"970\";}', 0);

MySQL-Fehler  : MySQL server has gone away

Note: Edited out the Board-URL as our Forums are "Not Safe for Work"

Is there anything I can do preventing this Error? The Pictures seems to be uploaded correctly.

2) My Users are moaning about the Add-On as it will "destroy small pictures".
Means if you have big HQ-Pictures of about 2000 px (or up) you will need a much bigger watermark to make it "visibe" even on big pictures, but then smaller pictures (reaching their threshold) don`look goog anymore.

So will there be any possibility to somehow add scaling to the Add-On; so that the watermark-sizes is set depending on this size of the uploaded picture.

Can imagine to pay for such feature; maybe you can drop me a line.

Greetings,
Bryan
