hi liz
contact info for IVRPA board of directors is here
http://ivrpa.org/about-ivrpa/contact-ivrpa/
IVRPA does not own the rights to any images on this site, all panoramas and other images are owned by that image’s author, and using any panorama or other image you see on the internet requires getting permission from the author, you will see a name or link on or below the image or pano showing author name, and you would need to contact this person and deal directly with them
if you are looking to create your own 360° images, we have a list of tutorials and other resources here

thanks
