Would've thought trying to block right-clicking on pictures died in the 90s, yet here we are. Trying to stop someone on the internet from saving pictures you've explicitly served them on your website isn't the silliest thing I can think of, but it's definitely up there.
To play devil's advocate, I can understand the mindset. People don't think in terms of servers and clients. This is more of a digital art gallery, and you wouldn't go and grab a photo off the wall at a real life art gallery.
