Sorry, no built in way to do it.
Free-format is one option to script the design in and make a custom layout for the task.
Off the top of my head, you might be able to put something into the footer and make it look like it's part of the MaxDiff task. It will probably require a little knowledge of CSS to minimize the white space between the task and the footer.
Another thought would be to use smaller images and tool tips so that the big images show on mouse-over.
