Header Image in Composer

Hi guys,
I am trying to add the header image from Composer to a custom page list,
could someone tell me what the handle is for this image?

There is no header image in Composer by default so this is most likely a Header Image added by either your Theme or an Add-On that you installed.

If you go into the Dashboard and go into Attributes under Pages & Themes you should see the Attribute Name listed there and if you click it you should be able to grab the handle from the edit screen.

Thanks hutman,
I have checked under attributes but can't see it there, I know how to show the Thumbnail:

$img = $page->getAttribute('page_thumbnail');
$thumb = $ih->getThumbnail($img, 120, 120, true);

page thumbnail also isn't listed under attributes, but still available?
I have attached a screenshot to explain it a bit more.
