TV6's Karen Cozier Phillip gives us a good example of how to write to pictures in the story of the little boy who has a degenerative disease.
When she says "...Hakim is confined to a bed or has to rely on his mother to carry him around...", we actually see him on the bed then his mom carrying him. That's the way to go.
Point to note though Karen. "Crippled" may not be politically correct. Maybe you can use disabled or physically challenged instead.
