Ortho Mapping - Refine Interior Orientation - Images not displaying in panel

[Tim_McGinnes]

Using ArcGIS Pro 2.7.3. I have successfully created my ortho mapping workspace for some scanned aerial imagery and now want to proceed to the Refine Interior Orientation step. However none of the images will display inside the Refine Interior Orientation panel to allow me to define the fiducials. Anyone got any ideas or workarounds?

It turned out this was the problem:

The Refine Interior Orientation panel was actually adding the photos, but they were not visible by default. And of course there's no way to make them visible again inside that panel...
