How do I do that thing where I get the photo to pop up in a little window?

When I highlight just 'walk', right-click and select evaluate selction, it displays a matrix of pixel numbers in the command window which I think means it's working to some extent. But when I highlight all of the code and click evaluate selction it just repeats my code in the command window and no image pops up. Furthermore, when I click on run it just displays "project1" in the command window.

walk = imread('walkstraight/frame0062.tif');
imshow(walk);

Perhaps,

walk = imread('walkstraight/frame0062.tif');
imshow(walk); shg
