Anything you put out there in the Internet (public pages) is available for anyone else to copy and save/re-use. So if you really want your content to be safe and protected - do not put it online.
But if you want you can try to protect your content/images and prevent/disable at least the most simple ways to copy it. In fact, anyone can "view source", check the browser cache for images, use "Print Screen" or "site copy" software, etc. - these things can't be disabled, but they require additional knowledge and skills than just selecting the content and copying it or dragging an image from browser window to the desktop.
