How to submit a picture with my verification code to verify the purchase of my paperback review.

When you choose to review a book as "Purchase a Paper Book Amazon as Verified Reviewer," you must show proof of purchase. To verify your book via picture, take a scrap piece of paper, write down your unique verification code, and then place that piece of paper on the cover of the book, ensuring you don't cover the title of the book. Then upload that photo into the Upload Photo of Book with Verification Number field in the "Submit Review" form.
