The other day I uploaded a photo as part of the check-in process for my cruise departing on the 18th May. All went well, and I printed off my boarding card. A day or two later I decided that the photo wasn't very good and that I would replace it with a better one. So I clicked on Remove, after which the space for the photo was correctly empty, then clicked on Upload, uploaded my new photo and - once I had it positioned correctly - clicked on Save. After which it reverted to showing the old photo that I had supposedly removed! Several other attempts were exactly the same. I suppose it doesn't really matter since, if P&O don't think the photo is adequate, I'll simply be photographed at the terminal on the day, but it's still annoying.
