Hi there and welcome
Any website that you use the photos can always be swiped, it's the nature of how websites work. The Microchip you refer to is metadata, but this can easily be removed, and only shows in the properties of the photo. Still the best and most reliable way is a watermark, and anyone serious about protecting the photo will use the water mark with the option for a customer to pay for it to be removed.
Was there anything else needed on this Steven?
