And another thing about Blurb

I forgot to mention the image requirements.

You can put in images in any size you want in the book and the software lets you shrink and move them any way you want within the image place holder.

If you want to have a full page image on the pages you need to make sure it is of a very high jpg or png file quality. When you ask your cover artist to make a background image, or when you buy images you need to make sure they are of a 300DPi resolution and large enough to fit the size of the book.
