title: I am not able to cache the images as I bindind Image using MvvmCross
body: <p>I am new to Xamarin Android Application.I use Picasso component to cache and download Images and It works fine.<br>
  <code>Picasso.With (this.Activity).Load ("Here I pass Url").Into (imageview);</code>
  Now I am using MvvmCross binding like:</p>
  
  <pre><code>&lt;Mvx.MvxImageView
     android:layout_width="120dp"
     android:layout_height="140dp"
     android:id="@+id/ProductImageView"
     android:scaleType="fitXY"
     local:MvxBind="ImageUrl URL" /&gt;
  </code></pre>
  
  <p>Here URL is a string which I set in Viewmodel.My problem is, it downloads image but can not cache that image like picasso does.Can anyone suggest me what to do?
  How to use Picasso to bind and cache image ?</p>
