You can see photos attached to scans in SCiO Lab (Web) by clicking Collections>Samples then checking the button for “Scans” (not “Samples”) then selecting the scan from the list.
Similarly you can see the photos in the Mobile Lab by clicking through your collection, all the way to “Scan (Date, Time).”
But I can’t figure out how to change or remove a photo after it has been attached to a scan during the pre-scan setup.
