Is there a function that will allow me to lock any pictures that I have on my website so that no one else will able to right click and save them.
There is always a way to save images on a site like that. A while ago, some websites tried to employ a practice of block right clicks on their pages, attempting to prevent users from right-click saving images. If you view source of the browser, you can still find the URL and save the path. There is no tried-and-true method for keeping people from copying images you don’t want them to have.
