hmm you will problary need this also (ThumbnailGenerator)

     public static Gdk.Pixbuf Create (SafeUri uri)
      {
         try {
            Gdk.Pixbuf thumb;

            using (ImageFile img = ImageFile.Create (uri)) {
               thumb = img.Load (256, 256);
            }

            if (thumb == null)
               return null;

            Save (thumb, uri);
            return thumb;
         } catch (Exception e) {
            Log.Exception (e);
            return null;
         }
      }
