The illustrations for my work are essential. The manuscripts which I send to the publishers need illustrations to bring them to life. Having said that, some of my books have a greater dependence on the illustrations than others. Dial-a-Croc for example has been read on radio and still works effectively, but books like Granny O’Brien and Cat have more than one layer and use what is called a visual sub-text (a story in the pictures which is not fully explained in the words). Without the pictures they simply don’t work properly.
