title: Android Picasso - Placeholder and Error image styling
body: <p>I'm using Picasso library for image downloading from the network. I just wonder whether I can use a progress dialog or a GIF image as a place holder? Also any idea on how to make place holder image to be smaller (and fit in centre) than the actual image that is downloaded?</p>
  
  <p>I tried going thru the samples but no luck. Any one here who got this to work?</p>
