Having a similar issue. If I copy a new image to a folder that has images that do work, the new image will come up as undefined when selected. I attached a screenshot. In this folder I can select the pdf but not the png image file. In fact, I can’t select this png image file from any folder. As a test I uploaded the attached screen.gif file to another folder that contains images I can select, but it also comes up as undefined when selected.
It seems images that I’ve had there for a while work, while new images copied into these folders don’t.
