Those are very different pages. Pinterest uses an image background, and home shop uses a revolution slider, not a header background.
You dont want the title on those pages, so disable that using the page editor and scrolling down to Theme General Settings – Title section.
Pinterest
Set the background image using page editor and clicking on the pencil icon for the first row. A row settings dialog will pop up. Set the background style to image, then select the image you want to use.
Home Shop
If you havent done so already, import the shop slider: https://archived.seventhqueen.com/documentation/kleo#revslider Import the home-default slider since that one is almost identical to the shop slider you see on the demo site. Once its imported, you can change the slider text and background image. http://previous.themepunch.com/revolution_wp/documentation/#!/slides_editor
