Improve this question

I'm building a website with lots of images and want to stop bots from accessing those images. So I'm looking something beyond cookies since bots can handle cookies. My idea is that all authentication should reside purely on the server side. Any ideas?

Someone suggested a website, that makes a user visit a thumbnail page first. Somehow visiting that page triggers a server side variable, which allows the main image to be displayed later. How can that be implemented.

That will stop some bots from spidering images on your site.

Also look into a .httaccess file
