TBC imports the files but all I get is the rectangle for the georeferenced image, no image.
Pat, I'm running 5.0, but I ran into this exact thing the other day when importing a large drone jpeg orthophoto (122MB).
I changed my display setting from "no tiles" to "tile with multi-resolutions" and it displayed correctly for me
I have the same issues with photos with to high resolution and choosing "no tiles" makes it work for me.
I haven't had this problem with 5.1 but did quite a bit with 4.8. Any older projects that I need to revisit need to have the PDF's re-imported. I've also set the image properties to no tiling with the highest resolution, it also seems to fix some of the quality issues. With very large geotiffs I've used a program called "IrFan View" to re-sample the picture, in many cases it can be set to UHD 8K and still reduce the file significantly and hold an acceptable image quality. Only down side is it's no longer georeferenced so it needs to manually be done.
