Step 2: In the sidebar, go to Revenue Management → Sites & Pricing and open the Sites tab.
Step 3: Click the site you want. Its details open on the right, with its photos. You can upload photos, reorder them and choose the main one right there.
Or: open the three dots at the end of the site's row and choose Site photos to open the site's photo page in a new tab.
*Note: you can upload up to 20 photos per site, which guests can browse in a carousel—so feel free to showcase the best parts!
