1) Different page header images for every page – Unfortunately this is not possible for different pages. You can change for all pages only in Theme Options->Header.
Just wanted to add for anyone else seeing this that there is an easy work-around if you want different page header images. On the right side of the page, you can disable “Show Page Heading” and then enable “Use Revolution Slider instead of Page Header” further down. You have to manually put a text layer of the page name on top of the image in the revolution slider you create for each page but it worked for us. We kept the normal page headers with breadcrumbs for all Woocommerce pages but then all others we put a revolution slider at the top with the page name and thus had different image for each page.
