When you or your guests zoom in on a property photo, the image can look soft or blurry.
Why this happens. The photo viewer can only display the pixels your property management system stores. Some accounts store listing photos at around 1024 pixels wide. That fills a phone screen at normal size but has no extra detail to show when zoomed. There is no setting on the website that can add detail the source photo does not contain.
What you can do. Upload larger versions of the photos directly to the listing in your PMS. The website picks up replaced photos on its next sync, and the viewer automatically loads a larger version when you zoom.
