If it is about WordPress Gravatar, you may fix it by adding below function using Code Snippet plugin.

function gatttf_replace_content( $text ) {

  if ( have_comments() ) {
    $alt = get_comment_author();
  } else {
    $alt = get_the_author_meta( 'display_name' ); 
  $text = str_replace( 'alt=\'\'', 'alt=\'Avatar for '.$alt.'\' title=\'Gravatar for '.$alt.'\'',$text );
  return $text;

add_filter( 'get_avatar','gatttf_replace_content' );

This will add alt tags to the Gravatar images automatically.
