Layout for part double pages: title on odd page, full size image on even page

This is an example of setting up the opening double page of a new part so, that the title of the new part is placed on the right/odd side and a full page image (including bleed) is placed on the even/left page.

Just replace all occurrences of "part" by "chapter" to do this for ... chapters :)
