It is a common thing that photographers and other users find their work all over the internet without getting asked for permission or even see a few bucks for their time and effort they put into something. One way to prevent people to just right click on your image and choose "Save image to...", "Save image as..." or "Add image to Photos..." is to add the following lines of code into your header file of your squarespace account.
If you are using Squarespace you just log-in to your account and and navigate to the following tab:
Settings -> Website -> Advanced -> Code Injection -> Header
This should help to make stealing your images a little bit harder.
