22. If I checked the option for photo optimization, do I have to use your stunningly gorgeous, optimized photos in my virtual tour and/or magic slider?

Stunningly gorgeous? Wow! (But yes, they are.) No, you are not obligated to use the photos optimized by Realitis. Our client has the ultimate say in which images they use. On our Realitis interface, you can compare the optimized photos with your originals. Pick and choose the best images for your project.
