title: Image orientation and validation with Paperclip?
body: <p>I'm looking for a way to determine image orientation preferably with Paperclip, but is it even possible or do I need to user RMagick or another image library for this?</p>
  
  <p>Case scenario: When a user uploads an image i want to check the orientation/size/dimensions to determine if the image is in portrait/landscape or square and save this attribute to the model.</p>
