You could always get some transfer paper and print pictures on it then iron them on! Not sure how good it would be for washing, but maybe you could print them onto calico, and then make them into little soft toys with a bit of wadding. Then you could use velcro to attatch them to the unit, so they can come off for washing, and can also be a toy.

The mention of my child's name may bring tears to my eyes,
But it never fails to bring music to my ears.
If you are really my friend,
let me hear the music of her name!
It soothes my broken heart and sings to my soul!
