How to prevent user from downloading or saving an image?

Question

Well, i have a web page where i am displaying few images. But my problem is that i don\'t want user to download or save those images. I can apply watermark to those images b

Answer 1

If the user can see the image, it's already on his computer. Saving it to a file or copying it to the clipboard is trivial and cannot be disabled in any reliable way.

If you want to keep control over the image, don't put it on the internet.
Watermarking is the best you can do.
