 Stop working after updates;
 One of our staff member report to me bug: problem with images in IE11.
  I didn't notice that in firefox  or chrome because images was resize to
 width and height set in img tag => <img src="some image" width="300"
 height="180" alt.. >
 but physical size of image is different the image have 1900 pixels width
 and 1028 pixels height, and was weight approx 550kb, its really slow down
 a website when we listing wordpress posts with feature image (which is so
 big right now) and our case study.

 I fix this by adding own resizing function and simply class, I declare in
 blog

 instead of:

 the_post_thumbnail('medium', array('class' => 'media-object'));

 this:

 $get_url = wp_get_attachment_url( get_post_thumbnail_id($post->ID));
 $local_small = Stefano_Resizer($get_url,300, 170);


 and in my theme functions.php:

 /RESIZE IMAGE


 class ResizeThat
 {
 var $image;
 var $image_type;
 function load($filename)
 {
 $image_info = getimagesize($filename);
 $this->image_type = $image_info[2];
 if ($this->image_type == IMAGETYPE_JPEG)
 {
 $this->image = imagecreatefromjpeg($filename);
 }
 elseif ($this->image_type == IMAGETYPE_GIF)
 {
 $this->image = imagecreatefromgif($filename);
 }
 elseif ($this->image_type == IMAGETYPE_PNG)
 {
 $this->image = imagecreatefrompng($filename);
 }
 }

 function save($filename, $image_type = IMAGETYPE_JPEG, $compression = 64,
 $permissions = null)
 {
 if ($image_type == IMAGETYPE_JPEG)
 {
 imagejpeg($this->image, $filename, $compression);
 }
 elseif ($image_type == IMAGETYPE_GIF)
 {
 imagegif($this->image, $filename);
 }
 elseif ($image_type == IMAGETYPE_PNG)
 {
 imagepng($this->image, $filename);
 }

 if ($permissions != null)
 {
 chmod($filename, $permissions);
 }
 }

 function output($image_type = IMAGETYPE_JPEG)
 {
 if ($image_type == IMAGETYPE_JPEG)
 {
 imagejpeg($this->image);
 }
 elseif ($image_type == IMAGETYPE_GIF)
 {
 imagegif($this->image);
 }
 elseif ($image_type == IMAGETYPE_PNG)
 {
 imagepng($this->image);
 }
 }

 function getWidth()
 {
 return imagesx($this->image);
 }

 function getHeight()
 {
 return imagesy($this->image);
 }

 function resizeToHeight($height)
 {
 $ratio = $height / $this->getHeight();
 $width = $this->getWidth() * $ratio;
 $this->resize($width, $height);
 }

 function resizeToWidth($width)
 {
 $ratio = $width / $this->getWidth();
 $height = $this->getheight() * $ratio;
 $this->resize($width, $height);
 }

 function scale($scale)
 {
 $width = $this->getWidth() * $scale / 100;
 $height = $this->getheight() * $scale / 100;
 $this->resize($width, $height);
 }

 function resize($width, $height)
         {
         $new_image = imagecreatetruecolor($width, $height);
         imagecopyresampled($new_image, $this->image, 0, 0, 0, 0, $width,
 $height, $this->getWidth() , $this->getHeight());
         $this->image = $new_image;
         }
 }


 function get_basename($filename)
 {
     return preg_replace('/^.+[\\\\\\/]/', '', $filename);
 }

 function Stefano_Resizer($get_remote,$get_width, $get_height) {
 $full_path = getcwd();
 $ar = explode("wp-", $full_path);
 $root =  $ar[0];
 $get_local = '/wp-content/uploads/images/'.get_basename($get_remote);
 $get_local_file = $root .'/wp-
 content/uploads/images/'.get_basename($get_remote);
 $image = new ResizeThat();
         if(file_exists ($get_local_file)){
         return $get_local;
         } else {
         $image->load($get_remote);
         $image->resizeToWidth($get_width);
         //$image->resizeToHeight($get_height);
         $image->save($get_local_file);
         return $get_local;
         }
 }

 its work and make a copy of listed images into declare folder of Stefano
 function.

 Would You fix that please?
 We don't like add any functions because we use widely Wordpress and
 maintaining a code that way would be problematic in a future.
 Btw. my head of development didn't allow to add new functionality so i try
 rise a problem here.
