Add image body to Lightbox2 pop-up image

Currently a LIghtbox popup image displays the image node's title, but it would be nice if the image module would optionally include the image node's body and/or teaser text. Below is my hack to do just that, though I don't know how to make this a configurable option. In the "image.module" file, locate the following function:

 function theme_image_display($node, $label, $url, $attributes) {
  // $img_alt_tag=$node->title; // Show image title only
  // $img_alt_tag = $node->title . "<br />" . $node->body; //Show image title and body
  // $img_alt_tag=$node->body; // Show image body only
  $img_alt_tag=node_teaser($node->body); // Show image body teaser only
  return theme('image', $url, $img_alt_tag, $node->title, $attributes, FALSE);
}

Notes

The middle four lines are new, but uncomment only the one you want. Each line re-defines the content of the Alt tag, which is then passed on to the final return statement.

Using the image node's teaser text lets Lightbox2 show a caption, but exclude detailed information.
