Don't even bother.
It is impossible to stop people from viewing source.
In your browser, on
any web page, go to 'File > Save Web Page As...'... You then have all their images and their source
There is however... One way of hiding your source. Don't put it on the internet
Whatever you do, don't disable right click. As it disable user functionality such as adding your site to their bookmarks, refresh page, opening links in new window, printing, going back or forward in their browser's history, etc.
The minute you visit a web site, your browser downloads the site onto your computer so you may view it- that's before you can do anything.
