Looking at this code, I am getting the sense that the timeout is happening because of an infinite loop. I am guessing that this happens at line 46 when the get_chapter_by_name is called, which will then try and return all of its paragraphs with images, not just image ids, and now the images call this function looking for its related paragraphs. I am going to take another look and see if I can straighten this out.

best,
