I'm working on a chapter style: link (pdf)
I want to use a different image at different positions in each chapter, sometimes even hanging into the title line (after the text), but the title line should always stay at the same height on the page.
How to define a chapter style that can be controlled this way? For both the book and the memoir documentclass.
(The book I'm working on is in book class, but I'd like to use this in some other projects which are in the memoir kingdom.)
