I don't know what this means. Do you want a multi-page tiff image? I've never heard of a multi-page (multi-image) jpeg file. Or do you want to stitch together two images so they make one tall (or wide) array with both images side by side?

  1. You cannot append to a JPEG.
  2. You num2str does not have an argument.
