title: image distortion issue in jCrop
body: <p><img src="https://i.stack.imgur.com/Cmb77.png" alt="iamge distorion"></p>
  
  <p>the html srouce code:
  <img src="https://i.stack.imgur.com/NvnpM.png" alt="enter image description here"></p>
  
  <p>That's rellay strange. I call the jCrop function when the image is loaded, I'm sure jCrop can get the real width and height of the image, but the resut is the image is distorted. </p>
  
  <p>Is there anyone encounter this error?</p>
