• Answer:

  You are not doing anything wrong. You have to wait. There are many problems with contacts this week. Yahoo is working on contacts and the work is causing problems. When the work is done, you will be able to post a photo next to each contact .... along with several other changes. A few people switched browsers to delete or edit the contact but you shouldn't have to do that. It may take a few days (weeks?) but Yahoo's engineers will get this fixed. One person just got a huge list of people added to his contacts today. He doesn't know any of them.
