Question about cover image
I have designed a book cover in Photoshop Elements according to your size specifications and is a jpg format. I might as well attach it, so you can see. I still have not tried converting the Word .doc into an epub using your wizard. My question is this. Does the wizard want a completely designed book cover such as this one for the cover image, or is it really just asking for a picture, which it is going to put in along with the title, subtitle and author and produce its own cover image. Also, then are the marketing image and the cover image and the book cover all separate or if not how do they relate?
