A Facebook Header montage of different photos

Facebook Pages are bringing in the timeline feature just like the personal pages and I need a montage of various photos reflecting the nature of the clinic (for which the Facebook Page is about) to be the header.

Facebook have told me that it needs to be at least 399 pixels wide and may not contain:
Price or purchase information, such as "40% off" or "Download it at our website"
Contact information, such as web address, email, mailing address or other information intended for your Page's About section
References to user interface elements, such as Like or Share, or any other Facebook site features
Calls to action, such as "Get it now" or "Tell your friends"

So I thought a montage of all the photos acquired by the clinic would get the point across about what the clinic does.
