How an image can be protected from download?

Question

How do you disable the "save image" option on the right-click, or just disabling the right-click on images?

Answer 1

Replace your image tag with this.
<img oncontextmenu="return false" src="whatever.png">

The users can still access the source code and save images without doing "Save Image As", through the Inspect Element option present in almost all browsers.

Answer 2
