My icone doesn't montrer up. Help?

Whenever I comment, mettre en ligne something, ou what not toi can't see my user picture. But go to my profil and you'll see my lovely Lost icon. O.o Also on my profil it shows only four little thumbnails where there's supposed to be six. I have pages of pics though.
So yeah, I don't know what to do. MDR I thought it would correct itself but it's been like this for days now. And I've tried uploading new pics but it doesn't make a difference. Anyone know what I should do? Thanks
