For loop to display images

So I am trying to make a for loop to display an array of images for a user to choose between two images and for the program to save the input data from the user (Left or Right), and then to go on displaying two more images to choose from. I understand that a for loop is needed for this but I don't quite know how to put it together. I have information, but it's very piecey. Any help is great because I am super new to MATLAB and I'm not communicating well with my lab adviser.

for K = 1 : size(ImagePairs,1)
  subplot(1,2,1)
  image(ImagePairs{K,1}};
  title('Left')
  subplot(1,2,2)
  image(ImagePairs{K,2});
  title('Right')
  drawnow();
  Q = input('Left (L) or Right (R)? ', 's'):
  answers{K} = lower(Q);
end
