The tool at the top of this page is built for photos that will be published on a listing. Every staged photo is compared with the original by code, not by eye: wall lines, window and door frames, and any new opening that was not there before. If something moved, the photo is retried once; if it still differs, you get the closest result with a plain warning, and that photo's credits are given back. The check is a second pair of eyes, not a guarantee, so look at every photo before you publish it.
Each photo also comes with a disclosure label drawn onto a second copy, in a corner and at a size that stays readable in a listing thumbnail. The default wording is "Virtually staged" and you can change it to whatever your market uses. You always get a copy without the label as well.
Some MLSs ask for the unaltered photo to be available next to the staged one. If you switch it on, the tool hosts the original beside the staged version on a private page that search engines are told not to index, and adds a QR code to the label that opens it. It is off by default, and you can turn the page off or delete the original at any time. Rules differ by MLS and by state, so check your MLS rules before you publish; the label and the page are tools to help you follow them, not a promise that a photo meets them.
A whole listing goes through in one run: up to 10 photos, one room type and style, and a ZIP of every staged photo with and without its label.
