Hi Reuben. I hope I attached the above file correctly. It is what I see when I go into edit book. I tried your code yesterday and it didn't work, no doubt because I entered it incorrectly. I have no other books in Calibre save for the one I'm currently working on, above.
I enlarged the cover drawing by a few kb's yesterday and it centered itself automatically, and unexpectedly, in both epub and mobi. They both present beautifully, but will I still need to center them anyway in edit books?
In epub, the drawings are justified left with a simple poem on the right. Once I convert to mobi, from epub, they all center themselves automatically!
I'm wondering if they will stay that way?
I thank you for your helpful guidance and will study it so I can learn it.
Kind regards,
Corinne.
