Several users got the error on the image attached when trying to import a JPG image on XTherion on Windows. One single user succeded importing a JPG image on XTherion on Windows.

These XTherions were able to import a PNG image.

They were all using Therion for Windows available at https://therion.speleo.sk/downloads/therion-setup-dev.exe

How can they import JPG images?
