You can also silence this warning when you don't care to know that your images are being displayed at a lower resolution:
warning('off', 'images:initSize:adjustingMag')

Hi Sara,
That is a warning, not an error. imshow is issuing this warning whenever it has to re-size the image to fit on the screen. In this particular case, you can safely ignore this warning.
If it is too annoying, then the best thing to do is to edit the call to imshow to set the 'InitialMagnification' parameter to 50 or 30. That will explicitly tell imshow to re-size the image, and will help you avoid the warning.
