var jQM = {};

jQM.ResizeImage = function (img, maxWidth, maxHeight) {
  maxHeight = maxHeight || maxWidth;
  var srcWidth = img.width; var srcHeight = img.height;
  var ratio = [maxWidth / srcWidth, maxHeight / srcHeight];
  ratio = Math.min(ratio[0], ratio[1]);
  return { width: parseInt(srcWidth * ratio), height: parseInt(srcHeight * ratio) };
};

$(document).bind('pagebeforeshow', function (e) {
  $(e.target).find("img.ui-li-thumb").each(function () {
    $(this).css('margin-top', ((80 - jQM.ResizeImage(this, 80).height) / 2)); 
  });
});
