Ability to scale the image on the end screen, or on any other screen if possible

I'd like to be able to scale the images that might be part of a multiple-choice question. I need the user to be able to see the full detail of the image in order to make their choice (ie. imagine that they're asked to pick their favourite logo). A zoom feature would be a compromise.
