My verification photo is awful as I just arrived for a tour ina London hotel to find my profile gone and the only way to get it back was to immediately send another verification photo so mine was taken with my hair still curly, no make up and a bit sweaty as was rushing to get my profile back as had bookings lined up for half an hour later. I hid the photo until I could redo it properly but they wont accept or allow another photo.
It seems AW always remove a profile during the night so when you log in for the day you find you have to quickly take a photo or have no work that day. I thinks its why so many photos look awful as you really don't have time to get done up to take it. (they also turn away photos if they think you are wearing make up now as well so its hardly a surprise some look so bad.)
