Miscellaneous Hacks - Watermark Attachments

Product: 1
Plugin: 2
Query: 0

tested only on the pure installation of vbulletin. install at your own risk to work with other attachment mods.

Feature

* put a logo (watermark) on your attachments.
* option to watermark only attachments after X days of creation. this helps your hotlinked images become free ads.
* option to watermark thumbnails but stop hotlinking to full size image (return a blank image instead)
* option NOT to watermark images for traffic from certain sites

Install

Step 1: import product-watermark.xml
Step 2: create and upload your own watermark logos. one for top and one for bottom.
Step 3: put the absolute path of watermark images into options. (/var/www/html/.../watermark.png)
Step 4 (optional) : if you don't want the attachments watermarked viewing on your own site or some other friend sites (like google image), just put the domains into "Skip Referer" option.

Not working
1. set the "Days Delay" option to 0
2. refresh your cache by press Ctrl-F5.
3. the watermark images should be in PNG format with transparent background.
4. check the "Safe Mode Temporary Directory" option. the directory should be writable.
5. only works for PNG, GIF, JPG attachments.
6. only works if the attachments are stored in the filesystem.
7. GD library should be installed.

Todo
* currently, we have to create a temp file while sending a watermarked attachment. It will be appreciate if anybody can help me to get rid of this.

Is there a way to get this to ignore .gif, it seems to want to mess up animated gifs

Hello,

It seems the watermark is not added when the image is not very wide (lesser width than watermark?). How can we make it always add the watermarkt please?

Great hack otherwise.

What a GREAT idea!!!

I still use vB 3.6.x Will this hack work on board?

Thank you!

AWESOME IDEA!

Unfortunately it doesn't work for me either.

I'm worried about the load this my place on a large forum, anyone notice? Why not just perm apply the watermark at upload, strangly enough, there does not seem to be a mod that does that.

Installed and WORKING on v3.7.4

Question: what are these options for? :

"Stop hotlinking to full size image"

"Skip traffic from some referers. Separate by commas."

^^ this last one, an attached image wouldn't even show up on another site because the user has to be LOGGED IN in order to view it anyway, right? So I'm not sure how another site could even display an attachment on their site in the first place ( ?? )

Shots of this modin action :

(note - the files in ^^ that url at the top of the page, the text in the bottom-middle of the first set of images was already hardcoded into them). The URL at the bottom RIGHT of each image is what this mod has added.

**ALSO**

For people bulk-downloading images off your site using programs such as BID (Bulk Image Downloader) - the watermark WILL be on the downloaded image. (which is excellent IMHO) Thumbs up on this mod!

I can't seem to get it working.

I think it has to do with the patch to the .png file.

not sure if I should add the /home in the path or not?

I also tried to put the full http://.........../watermark.png and that didn't work either.

Any ideas?

woot! been waiting for this...

REQ: is there a way to make it USERGROUP dependent? (make exceptions).

there are sometimes when its not appropriate for us to watermark (like a signature) or contest. And I want to have an option for some ppl or usergroups to be excluded from the watermark.

great work.

.. at least it does this when installed on v3.7.4

attachment will not be watermarked if the width of attachment image is smaller then the width of watermark image.
