A picture book is a book designed for children which uses pictures and illustrations to tell a story. In some cases, a picture book may convey the meaning of the story entirely through pictures, without any text at all. In other cases, text accompanies the pictures and is read along with them.

Picture Books are books in which the pictures are as important as the text or only consist of picture which when put together tell the story. This is a genre based on a physical format, so it can contain titles from many of the other genres.

Pictorial writing, synonymous with visual storytelling, is an expressive narrative form reliant on a sequence of images to unfold a story, elicit emotions, and communicate information.
