WordPress - Show image title only on attachment page

Goto header.php and find the part between tags.
Suppose it is:
Replace this code with:

<***?php

if (is_attachment()) {
 echo $post->post_title;
}else{
 get_title();
}

?>

 remove this ***

And now go to all in seo plugin.
Add this to line 92 of aioseop.class.php in wp-content/plugins/all-in-one-seo/

//added by nabeel
  if(is_attachment()) {
   return;
  }

before:

if (is_feed()) {
   return;
  }

Now your wordpress works normally with all in one seo plugin but the attachment page titles are not stuffed with keywords anymore and contain only the image title
