title: symfony image upload resize
body: <p>I'm using symfony to develop a website and have it mostly functioning, but I need it to resize images to a certain size when they are uploaded. I installed the sfImageTransfomPlugin to allow me to resize them, and figured out that I need to overload the save() method in the model class, but I can't find any documentation to get the information about the uploaded image so that I can resize it. Has anyone done this before or can point me to some documentation for it?</p>
  
  <p>Thanks in advance.</p>
