Changing image display in

In the public display part of the Omeka site I am constructing ( the image appears at the bottom of the page. I would like it to appear at the top. Is there a way to make this happen? I can see the code that needs to be changed, but it doesn't look like I have access to any of the php files in the hosted version. Thanks for any help you can provide.

Yes, for the hosted version, we can't allow access to the PHP files for security reasons.
