Question/
How I can protect images as the user can click on it to view its large version, once clicked into the file URL, users can right click and save images!!
This happens with me with Media library images & on my pages or posts with image url over it, They are not protected?
Answer/
The thing you must know: There is no way to protect any image if you view it with its full URL (example: http://www.sitename.
So you should fix the problem by stop displaying a link to the full image over it
Just Edit the post or the page and remove the links over your images or you may find a (removing links) plugins that will do that for you in one click, Also we have an option to do this for you on the fly inside the smart protection tab
on the fly = you will not see the links but the links are not removed permanently and when the plugin deactivated everything return as it was before
if you still want to view large photos when a user clicks on your images and also keep them protected we advise using (simple lightbox plugin) (https://wordpress.org/
you will have a magical mix
