I'm building an email campaign and want to create a consistent header style for sections in my newsletter. Basically I have some plain text that will serve as the title for each section, but I want to put the text on top of an image that is the same for all sections. I have an image and I've tried using the module editor, but I can't get it to work properly. Can anyone provide simple instructions for doing this sort of thing? Seems rather basic to me.
