*I am a PBI desktop newbie* but I've spent a few hours looking for the answer and trying various suggestions. Seems that the ImgViewer custom visualization only works with urls that point to public web pages. I can get it to display the correct ImageURL as text, not the actual image, although I have made the data type ImageURL. I even added the folder containing the images as a data source, but that didn't seem to accomplish much.
Is this possible (without gymnastics in R or other workarounds) or not?
