Blocks missing additional block element

I am trying out Drew's Block Template, have tried to modify it but wanted to add a Large Image Block. When I check in the admin area I see Text : Pull Quote : Medium Image : Inline Image but the additional Block Large Image is not showing. Clearly I have missed something? By the way the other elements work brilliantly.
