Converting from Quark?
Book Design and Imaging
I really wish Blurb would accept PDFs for this, it would be so much easier for professional designers to create books.
You can create a batch in Photoshop, though, to automatically convert all your EPS files into PNG or JPGs. Record an action and apply it to a batch process. This way you can just let it roll and go get a bite to eat while the computer does the work for you!
Hope that helps!
