Chang header and background image in each page

I’m new in wordpress and I’ve two question,

  1. Is it necessary using child theme ?
  2. If I want to change header image and background image for each page,what should I do?
    I will be grateful if some body help me .


  1. You don’t have to use child theme. Child theme usage is advisable only if you want to modify theme files or functions. When you are using child theme, these changes will be permanent after theme updates. You can read more about child theme here

  2. You can check moesia documentation regarding individual header image (section 12. Single pages header images).
