FYI, Spoke to someone in Tech Support and solved the problem. He suggested I enable "Unified View" under the "View" menu. That fixed the problem. Now when I export to JPG, I get an actual image instead of all black.
I have the same problem. Image is black when I export Image File as jpg, png, or tiff. works fine to PDF. What am I doing wrong here? worked for years until I updated to VW2021
