IBJoel ...a bit more info for you to hopefully unravel this issue. I'm now starting to be able to insert images in my TR, using the process from 'landscape icon'.
The "Download files' screen does, however, take a good minute of so to become fully functional (i.e. the 3rd button appears and all other buttons eventually work). I'm therefore able, incredibly slowly, to re-populate the TR.
So this is Qatar Airways? UK-South Africa with QR (and a bit of BA).
This will take a couple of days at this rate, as there's over 70 photos involved. It's taking me 4 minutes per photo to replace!!
