Hello all! Can you please help me, and tell me why that when I change my profile picture to just a scenary photo from my RL photo. It will show as it's changed. But I always get IM from others, saying that "OMG! You look pretty in RL". The heck? So apparently, they still see my previous photo. I can't see it on my end. Is something wrong? It happened to me more than once thank you!
