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.

Great Mod, But I can't get it to work with VBSEO when using a CDN, when i attach images they don't show, when looking at the properties of the image it shows that they are stored on the CDN..

Hi

In the adminCP, does the watermark appear on the sample image?

Did you specify a cache directory and does cache files appear in this directory?

No, no image appears there at all, but during the Preview Mode, no image is diaplayed at all either, which I thought was odd because the instructions refer to the "image below" and it's not there.

Yes, setup and specified a cache directory which appears to be accepted. No, there are no files in the cache directory. Also, in the Cache Stats screen if check yes and hit submit, I get a phrase missing error. See attached pic

The cache directory doesn't seem complete to me, are you sure that's either a full path starting with a "/" and the directory exists and is writable or a relative path to the forum root dir starting without a "/" ? (Usually the web directory is somewhere around /var/www/htdocs/ or /var/www/vhosts/domain.tld/httpdocs, so it looks a bit odd to me)

The missing phrases don't have any impact on the functionality, it's just localized text which isn't found. That's something I'll fix in the next version.

If the cache directory isn't the problem, follow the instructions in this post: https://vborg.vbsupport.ru/showpost....42&postcount=5
If there are error messages, they can be displayed via this script.

[BadgerDog]

Cache full path is there.... I just removed the front part for security reasons showing it public here.

I'll try the instructions in the other post tomorrow and let you know.

Thanks for the help.

Problems on VB4 which installed of vB Optimise, all cache flushed too.

[Stefan118]

haven't tried it, but maybe you have to set your cache directory to 777 (writable)
I did that at forehand, and it works on my vB 4.1.3

Hi ...

Ok, the output is an SQL error. For security and privacy, I have replaced our site name with xxxx's.

Database error in vBulletin 4.1.3:

Invalid SQL:
SELECT varname, value FROM plwmsettings;

MySQL Error : Table 'xxxxx.plwmsettings' doesn't exist
Error Number : 1146
Request Date : Sunday, May 22nd 2011 @ 06:30:30 AM
Error Date : Sunday, May 22nd 2011 @ 06:30:30 AM
Script : http://www.xxxx.com/testattachments.php?i1=22804
Referrer :
IP Address : xx.xx.xxx.xxx
Username : Tester
Classname : vB_Database
MySQL Version : 5.0.77

The SQL error doesn't appear when I run the "Preview" or try to view the same attachment with the mod's code, just run I run your special testattachments.php program.

By the way, I have re-installed the mod twice just in case something went wrong with the original install.

Does this help?

Doug
