Preventing a visitor from saving an image from my site
image
Solution
It's not possible to make it "impossible" to download. When a user visits your site you're sending them the pictures. The user will have a copy of that image in the browsers cache and he'd be able to access it even after he leaves the site ( depending on the browser, of course ). Your only real option is to watermark them :O
Problem
What are some effective strategies for preventing the use of my proprietary images? I'm talking about saving them, direct linking to them etc... Presently I have a watermark on the image, but I'd rather not. .NET platform preferred, but if there's a strategy that's on another platform that integrates with my existing application that'd be a bonus.
