I can barely imagine that. If an image is longer, it always automatically will become shorter. You can see it on my page as well. Those are full sized images, but they automatically adjust to the box size.
you cant repeat an image. I advice you to remove the right panel, and make a seperate intoduction panel like mine. There also seems to be something wrong with the coding since (atleast on my laptop) the left half of your text box is completely gone.
