Thanks for all your help. Using Magick had no effect so I've had another look at my setup. It turned out I had this in m \setupexternalfigures [maxwidth=\textwidth, maxheight=0.8\textheight. location={local,global}, ] The period to end maxheight is obviously a mistake. (However, I'm still perplexed that this only shows up when the image is rotated...) Sorry for the noise. Denis

You could try making a new image with the same content. Assuming you're on Windows 10/11, install Image Magick
winget install -e --id ImageMagick.ImageMagick
then run
magick convert -strip image.jpg temp.tga magick convert -strip temp.tga new-image.jpg del temp.tga
which should give you a new image "new-image.jpg" that shouldn't be corrupt. If you are still having problems with this new image, then the issue is likely with ConTeXt itself, and this specific image is just triggering it somehow.
