I'm going to add this as a comment instead of an answer, because I'm hoping someone else will chime in. There are posts on how you can print your whole family tree, but some of the techniques involve downloading your GEDCOM file, and that wouldn't include photos (still, you might want to search for them). I think you can probably download a single sheet PDF file and use Adobe Acrobat to change to a large page size for having a large copy printed.
