Attached Image Watermark

This plugin will watermark attached images on your forums. works on 3.5.3 for sure, probably works on others as well.

Simply upload new Plugin, Then Edit the Three Following lines, then Activate plugin.

Edit this line to match your watermark file:
$WATERMARK_PNG_FILE = '/home/ntfu2/public_html/watermark.png';

Edit this line for bottom or centered
$WATERMARK_POSITION = 'bottom_left';

You can test with your userid only first, Edit this line
$VB_USER_ID = 0;

ATTACHMENTS MUST BE IN FILESYSTEM

does not support .gif since it will stop any animated gif from playing. watermarks, .jpg and .jpeg You can probably add code to watermark others.

If you use it click install, i'll try to give support, but only to those who install
Edit: UkJimbo made this modification for me, i paid for it, so therefore i am releasing it to the public

Enjoy!

Try uploading a fresh image,

make sure your attachments are in the filesystem and not the database.

if viewing old attachments press CTRL+F5 to maybe try to recache it

[shadyninja]

what does this need to be changed to....
to be able to move them to the file system

We attempted to write a test file to /path/to/your/attachment/directory, but we were unsuccessful. Please verify that the web server has write/delete permissions for this path.
?

You'll need to chmod the directory to 0777 that you set in the adminCP, you can do it either FTP usually with a right click -> permissions or via SSH command

chmod -R 0777 /path/to/your/attachment/directory/

*I'll assume a 5 year old got far enough to import the plugin*

1. Login to your site using your FTP program (the way you uploaded your vbulletin files)
2. Create a new directory outside of the public_html (or www) folder called 'attachments'
3. Right click on that new folder you just created and look for a way to change its permissions, enter 0777 for its new permissions
4. Go to your site
5. Find the AdminCP link
6. Login using your administrator details.
7. On the left hand side look for ATtachments
8. Hit the Blue arrow to make a drop down, and reveals Attachment Storage Type
9. either move them from the Database into the filesystem, Hit the go button
10. set the folder to your attachment folder you created in step 2, should look something like /home/site/attachments

That should move your attachments from database into the file system

[shadyninja]

ok thanks
I now feel 6 years old!

[shadyninja]

hmmm
"Right click on that new folder you just created and look for a way to change its permissions, enter 0777 for its new permissions"
I thought I knew what you were talking about, but when I got to the folder, there wasnt a way to change permissions
