Also if you've already converted the book before then the damage has been done unless you have your original un-split source.
The only other reason for page breaks is if they were previously defined in the html/css.
The "book" is something I am compiling a chapter at a time. I accomplished this once before, with another project, using an earlier version of Sigil and it worked flawlessly. I am using the same css as before but haven't figured out why the images are not remaining at the beginning of each chapter this time around.
I suspect my lack of experience/knowledge with html isn't helping or it would probably be obvious.
