When setting up Family Sharing on iOS8, I can set up a photo for my family user (the same photo will be used for the iCloud account) by going to Settings > iCloud > Family Sharing. The dialog allows me to select a photo, move it, resize it.
Once I have selected and confirmed the photo I want to use, is there a way to change the photo again? Holding a finger on the photo doesn't have any effect. I haven't found a way to reset or change the photo.
Is that something that Apple has not thought about, or am I simply missing something?
