I tried to use this code below to add titles "1" and "2" to my images, but only "1" shows above the first image.
Could anyone help me with this? I want to show "1" above the first image, and "2" above the second.
Thanks in advance.
subplot(1,2,1),imshow(I1),title('1');hold on
subplot(1,2,2),imshow(I2),title('2');hold off

Ran in:
Yes, but that's not an error. Did you actually receive an error (some red text)? If so what is it?
Your code is working as expected. See below:
What did you expect would happen when it hit the "figure" command on line 4 of your code above (line 6 of my code below)?
Im1 = imread('cameraman.tif');
Im2 = imread('moon.tif');
drawnow; figure; % Create first figure window.
imshow(Im1);
title('image 1');
drawnow; figure; % Create a separate, second figure window.
imshow(Im2);
title('image 2');

By the way, the call to drawnow should come after you draw something, like after a call to imshow and title. Do not call it before you have even drawn anything.

What you want to happen is actually what DOES happen:
I1 = imread('cameraman.tif');
I2 = imread('moon.tif');
subplot(1,2,1),imshow(I1),title('1');hold on
subplot(1,2,2),imshow(I2),title('2');hold off

If you want, you can explicitly put the axes handle in:
h1 = subplot(1,2,1), imshow(I1, 'Parent', h1), title(h1, '1'); hold on
h2 = subplot(1,2,2), imshow(I2, 'Parent', h2), title(h2, '2'); hold off

what if I want to title two different imshow with different title. lets say
imshow(Im1);
title('image 1');
figure;
imshow(Im2);
title('image 2');
matlab is showing the two pictures but the first title has been crushed by the second one, and the second imshow has no title.
