Load image with jQuery and append it to the DOM

$('<img src="'+ imgPath +'">').load(function() {
  $(this).width(some).height(some).appendTo('#some_target');
});

If you want to do for several images then:

function loadImage(path, width, height, target) {
    $('<img src="'+ path +'">').load(function() {
      $(this).width(width).height(height).appendTo(target);
    });
}

Use:

loadImage(imgPath, 800, 800, '#some_target');
