Sorry, but these graphics-oriented textbooks and coffee table display items simply are a no-go on hand-held readers, even tablets which are uncomfortable to hold for long periods of time and suck batteries to death in shorter periods of time. There are some things that are better in their original paper format where the printer can fit the page size to the graphics requirements of the work.
What I would suggest is having a pure text display with a full-screen toggle to the graphic or image if it's really an integal part of the book. Panning on smaller-than-book-page-sized screens is as absurd and annoying as not being able to see all of a spreadsheet or photograph on your computer screen and having to mouse around to work the scroll bars. Zoom functions require yet more graphics and battery power which results in shorter charge life and more weight.
In addition, it is the cash-strapped student market that will be most opportunistic at finding ways to bypass DRM-like restrictions with which more mature readers are reluctantly willing to live.
Forget it for now.
