Add custom message below image but above description?

Hey,

I wanted to add a message on each image node page under the image preview, but above the description (sort of sandwiched :P.)

I dived into the image.module searching for where I might do this, found:

  // Build the node.
  $node = new stdClass();
  $node->type = 'image';
  $node->uid = $user->uid;
  $node->name = $user->name;
  $node->title = isset($title) ? $title : basename($filepath);
  $node->body = $body;

Thought it might be in that general area where I'd add a statement to output a message in a custom div class.. Tried a few different things, but none of it seemed to work.. Am I looking in the right places..?

Basically the message would be "Share this image with family and friends! and then I'd output the current url onto the page using

$url = (!empty($_SERVER['HTTPS'])) ? "https://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'] : "http://".$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
print $url;

or something."
