Plugin for others to easily download photos?

I’m a photographer who is going to be taking photos at some non-profit events. I will then post the photos on my website for people to download. Is there a plugin that might help make viewing and then downloading the photos easier for non-tech savvy folks? Perhaps the plugin would allow them to select multiple photos and click a download button instead of right clicking, etc?

Thank you!
