This field shows the full disk path name of the image associated with this Photograph.
When this property is selected, the “Replace photo (retain orientation)” hypertext control appears. Clicking this will allow you to select a new replacement image file or sequence of images, while retaining the orientation of that photo. This is useful when you have stationary camera(s) and have a repetitive project setup, where you are confident that the camera has not moved. This allows you to re-configure a measurement project without setting up a new project from scratch.
