Has made so:

$(function() {
  var url0 = "1.jpg";
  var img0 = $("<img src=" + url0 +
">").appendTo(document.body).hide();
  var w = img0.width();
  var h = img0.height();
  alert("//--> h=" + h + ", w=" + w);
});

It works, here results in different browsers:
IE:      //--> h=700, w=581 - It is correct
Opera:   //--> h=700, w=581 - It is correct
Firefox: //--> h=1002, w=1002 - It is wrong :-((
Safari:  //--> h=0, w=0 - It is wrong :-((

Whether it is possible to make so that in Firefox and Safari results
were correct.
