How to add background image in Pages?
Pages has consistently proved itself to be very counterintuitive piece of software. I searched the web for almost an hour without a good solid answer to this question.
What I want to do:
1. Add a transparent png as my background, with a cut out center to be used for my content (basically a custom document border).
2. Have that background automatically replicate itself on every following page.
3. Be able to type over the entirety of the image if I want, and after reaching the bottom of the page with my text, have Pages automatically create another page for me with the same layout.
Color me ignorant, but all of that seems impossibly hard to figure out on my own just by poking around / reading tutorials / searching the web for answers.
Help?
