Re: w3c compliant coding and buddypress
hi Andy
You were right.I just changed one line in bp_core_fetch_avatar and it worked .No more ids ,no more problem 
I changed
return apply_filters( 'bp_core_fetch_avatar', "<img src='{$avatar_url}' alt='{$alt}' id='{$css_id}' class='{$class}'{$html_width}{$html_height} />", $params );
to
return apply_filters( 'bp_core_fetch_avatar', "<img src='{$avatar_url}' alt='{$alt}' class='{$class}'{$html_width}{$html_height} />", $params );
Thanks
