Prevent visitors from using photos

Hello,

I don’t want to put a logo on the photo  and I didn’t manage to disable the right click. Someone can help me please ?

Thank you so much !

Disabling the right click won't stop anyone who wants an image, they can just left-click and drag it onto their desktop or they can take a screenshot. No point in disabling the right click. Your best solution, and I don't like it, and won't do it myself is to watermark your images. That is it, NOTHING else including Hotlinking  will work.
