How can I protect images on my website from being downloaded?

There's not much you can do to fully prevent downloads. Even sophisticated bots can easily take screenshots. But instead of worrying too much, think about serving lower-resolution images to premium users.

You can make it a little harder for casual users. One trick is to use a CSS background image. This stops right-click saves and is effective against most users. You might also try applying a transparent overlay.

If you really want to complicate things, consider resizing the images or applying transformations like flipping or rotating them before rendering. This makes the downloaded image less usable. But remember, nothing is foolproof!

Honestly, it's a tough battle. Any image displayed in a browser has to be downloaded in some form, so complete protection isn’t possible. If you sell images, consider adding watermarks server-side to deter unauthorized use.

Yeah, there's really no way to make it completely secure. Everything sent to the browser can eventually be saved in some form. You can only aim to frustrate the typical user.
