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.

Another follow up ...

I think I found a pattern with the grey bars, but it doesn't make any sense. It seems to only happen, at least on our site, with pics that are very large when expanded to full size, from their small thumbnail. I don't mean size as in bytes, but rather size as in HxW dimensions.

Regards,
Doug

I couldn't yet find the reason to this behaviour, it seems to be webserver-specific... still working on it.

Thanks .. :up:

Update ...

Did so more research and there's definitely a pattern of only grey bars appearing for pics over a certain HxW ...

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:

Regards,
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).

Working on it right now.

The thing is... The url "http://nycjdm.com/testattachments.php?i1=2006-I-drive-a-eg-4-door" seems to be completely wrong.
Did you enter it by yourself? Because that's not the way it was intended, maybe you misunderstood the parameter?
Or did the script redirect you to this url?

Lets say you browse your album, you should find the id even with seo urls enabled. Check the screenshot where to find it:
Attachment 129906
You'd then enter the id into the test url like this:

http://nycjdm.com/testattachments.php?i1=13

This way, the test script will use the image with id 13 for the testing.

Okay i understand now.. i redid it and i got this error

Failed @ 114

[Disasterpiece]

Just updated with Version 1.1 which should fix a few problems

Okay i understand now.. i redid it and i got this error

Failed @ 114

Open the testattachments.php with a texteditor, search for the line

PHP Code:

if (!$res) die("Failed @ 114"); 


replace it with:

PHP Code:

if ($res === FALSE) die("Failed @ 114"); 


and run again. Then report back if it still fails at the same error.
