title: titanium studio save image into the native gallery
body: <p>i would know if it's possible to save an image (from imageView, retrieve by webservice not from the camera) in the native gallery, both on ios and android ?</p>
  
  <p>I suppose that yes, but i can't find the native gallery path to use for saving file (like Ti.Filesystem.externalStorageDirectory).</p>
  
  <p>thanks</p>
