Copyright images & too many clicks may turn off visitors

To use this site for artists does anyone know when you add an image to the post as a feature image and then you click on “Read More” and it brings you to the post page, you can add that same image within the post text box (yet the image is so small to impress anyone in my opinion), but if you link it to its own URL, you can click on it and you will get a larger version of it. Ok but will any visitors bother to click that many times to see a beautiful piece of your work? Also there are plugins that protect artist’s copyright work but you are able to right click this image and save it even with the plugin I installed. I am going to watermark all my work but is there a way
1) to enlarge your images within the text area of a post without them getting blurred and to eliminate so many clicks to the final enlargement
2) is there a way to protect your work, such as a plugin that is compatible with this theme?

I just started working on my site with this theme but I have a test image up temporarily on disanovisions.com
Appreciate it
