Missing avatars ?

Hi all.

After i have moved my wordpress folder from sub domain to my main domain my avatars are gone and it just shows a pic of its not there.

And if i see in my standard avatars in the discussion part in my admin cp it shows the same picture on all like its not there.

How do i get my avatars back or how do i get the oppotunity to make it so i choose to upload one so i can use my own one ?

Best regards
