Once the photos are displayed, visitors to the site can simply right-click and save them.

Or is something else intended?

As Daniel tell it is possible to download all what is shown in the browser - and also when you have disabled right-click.

You should only use images in a rather low resolution and maybe watermark them. The images for download could be in a better resolution.

Even if you make the links on restricted pages you should be aware of that crawlers can find the images and maybe display them in a search-result.

You could zip the images and also supply them with a password. This way they will be useless for a user that maybe has found an image - he will not be able to open the image.

For your customers you could inform them that the images is available via the links provided, that the images is password protected and that they should use the contact-form and that the password is included in the reply they will receive when they use the contact-form.
