Watermarking for attachments and imported images

[RichieBoy67]

I think Vbulletin really needs some watermarking options that are updated and fully functional. Many Vbulletin sites post thousands of images and a mod like this would surely do well here.

As many others do I use a mod to import images that remotely hosted. Those need to be watermarked as well.

The watermarking plugs now seem to basically duplicate the images which uses a ton of hard drive space, makes back ups take longer etc. I would be fine with my images being overwritten with semi transparent watermarking images added.

What do you all think?

Thanks,
Rich

the problem with not duplicating the image is if your watermark changes, or you need to supply the original unmarked image, you would be unable to. However, if you were to use a javascript based watermark, maybe something like this: http://brianium.github.io/watermarkjs/

Htaccess could also work but would not actually overwirte the images. Replacing the images would be good for when people actually download the image but other than that an on the fly scenario like htaccess may work.

I will check out the link! Thank you!

javascript would keep the watermark when downloaded, yet not actually edit the image in the filesystem

Seems like a great method but I am not sure how to implement it just yet.

Thanks!

I will try and take a look at it this weekend, just remind me closer to Friday, lol
I make no promises though, as I have not yet worked with the image/attachment systems

[RichieBoy67]

Thank you so much! That would be amazing!

The javascript method works well for the reasons sited but is easily circumvented by the "view source" context menu.

This is the watermarked image on the javascript page.

True, but unless you want to edit the original image, or store multiple copies there are not many other options.

Agreed. Most people don't know what the view source option does anyway. It's impossible to fully protect content from everyone.
