After you call imshow() call axis():
grayImage = imread('image.jpeg');
imshow(grayImage, [], 'XData', [0, 50], 'YData', [0, 77]);
axis('on', 'image');

You can use flipud() on the variable as you pass it into imshow():
grayImage = imread('image.jpeg');
imshow(flipud(grayImage), [], 'XData', [0, 50], 'YData', [0, 77]);
axis('on', 'image', 'xy');
Or reverse the numbers for YData:
grayImage = imread('image.jpeg');
imshow(grayImage, [], 'XData', [0, 50], 'YData', [77, 0]);
axis('on', 'image', 'xy');
