My problem is that Sharepoint 2010 sets by default a wrong profile picture which owns to another profile to some profile which don't have any one. But next, some profile who don't have any profile picture keep the Sharepoint default picture for missed picture. I don't understand where it comes from but I think it is during the User Profile Synchronisation because when I look at the Profile DB I can see that there is a good photo URL corresponding to the name of the people but when I go on this URL there is the wrong picture.
Thank you with advance and excuse me for my poor English.
