Показать описание
Protect photos and images from unwarranted use with watermarks in JavaScript using Cloudinary.

We'll walk through how to overlay an image as a watermark on a photo, resize, and position it for ideal placement using the Cloudinary JavaScript SDK. We'll then add text to an image to serve as the watermark, as well as see how to change the color, font, and size.

Yes, however from my experience, many users on Facebook simply copy and use watermarked images without "second thought" are these users seem blind to the watermarks in the images they use. (Copyright ditto)
Given that, it would seem wise to design watermarks to be also "subliminal advertising" for the image source. i.e. a clearly recognizable logo or name.
Secondly, it is very sad that the Cloudinary anti-hotlinking feature is now a paid feature, and no longer free. It worked well to stop image bandwidth theft.
