The BookReader will serve pages of variable widths.  You can see an 
example here if you flip through the book and then look at a map:

You need to click and hold to drag the oversized page if it bleeds off 
the screen.  If you simply click, the page will turn.

Take a look at the demo that comes with the BookReader distribution:

See how the br.getPageWidth and br.getPageHeight functions are hard 
coded?  You need to set them dynamically.  In the Ethnographic Maps 
example I gave above, our metadata contains the archival image 
dimensions, so we use that to set the height and width before it gets 
loaded.  Are you using an image server? Djatoka has a metadata service 
that you can query, which might be an alternative if you don't have 
image dimensions.

Building off the demo assumes a fixed width/height ratio, which in our experience is not always the case (consider the book with the occasional map foldout).

My current hack has "auto" filled to the width, which breaks centering and thumbs, but renders the odd page as legible.
