Override the Guest Author

guest_author_disable();
get_avatar( get_current_user_id(), 100 ) //now get the original avatar
guest_author_enable();

 

Override userdata.

In version 3.0+, the author query for guest author post archives now returns the guest author data in the queried object field. You can add this code to your custom theme functions or override the pluggable get_userdata function by adding this code.

if ( is_author() )
{  
      
   global $wp_query;
   if ( isset($wp_query) && $wp_query->is_guest_author )
   {
            if ($wp_query->is_guest_author)
            {
