[Fivestones]

Hello ,, Here is a picture of what i get ..... If i post a message and dont use a icon picture in it i get this Defualt picture ... And even if i post a reply to a post i get the same thing ... And when you reply to a post you dont evern have to use a icon but this Default still comes up..

I added a Home page to my site do you think that may have done any thing to my postes ???
