title: JPG cropping in batch to generate square thumbnails
body: <p>I am looking for a light weight batch tool for cropping image files.
  The cropping to be done around the center since the aspect ration can be 3:4 or 4:3
  This means for taller images, crop will happen at top and at bottom to generate the square image.
  For wider images, crop will happen at the left and right to generate the square image.</p>
  
  <p>Anyone has used such a tool? I am using .NET 4.0 and C#</p>
  
  <p>I am not looking for ImageMagick or nConvert.</p>
