body: <p>I'm looking for the best way for loading user avatar for rails app.</p>
  
  <p>There is some of important cases:</p>
  
  <ul>
  <li>load images from web or local</li>
  <li>allow user crop image at preview window (with Jcrop for example)</li>
  <li>save several sizes of avatar 64x64, 128x128, etc (Carrierwave or Paperclip no mater)  </li>
  <li>easy styling and customizing</li>
  </ul>
