@jwojo downlaod the file without changing it’s default extension
After you download the file as .webdev (or whatever the default extension is), go line tile to convert it to jpeg “google convert .webdev to .jpeg”. That is what worked for me.
I have a suspicion that some jpeg files aren’t actually in the right .jpeg format. I say this because when I tried different files it worked. I’m not sure why but I assume something is wrong with them internally I guess.
