is it possible to make all images “save” so that they can’t be downloaded from the website? For example in my portfolio as it is now the images can be dragged from the site. Is it possible to lock this?
there is no easy way to achieve that, for once because a visitor can always take a screenshot of the page with the image and cut out the image from it. The most widely recommended way of preventing unwanted image theft is watermarking; you can also consider using a password-protected area to hold the full-size images.
