I just had the same happen to me for the 1st time when trying to login to My Alamy using my iPhone. A set of pictures appeared and had to click on the ones containing signs, (not easy on a small screen). After clicking a few, I click "verify" and it appears to take me straight back to the original login screen. At which point I assume I must have got the answers wrong, so I click login again (as my login details are already filled in automatically by Safari) and go through the whole process agai
