How to change the header picture in a new page?

I created several new pages but the image seen in the header/title banner (not sure how that area is called) is the same on all pages - I would like to be able to place a different picture.
The theme is Chiropracto - Physical Therapy WordPress Theme by Designarc.

Thank you for your help.
