So after reading some of your comments, I went back and edited my roller post anyways. Now there's pictures! And I figured out how to make the page break. Turns out it was hiding in front of me all this time. There's a "Insert jump break" button on the blogger interface when you're writing/editing a blog, it's to the right of the "Insert a video" button and it looks like a... page being ripped in half. Funny and annoying how things can hide in plain sight huh?
