/* Image Information such as size and mime types can be returned with the getimagesize() function... here are a few useful examples */ 

<?php 
$size = getimagesize ("img/flag.jpg"); 
echo "<img src=\"img/flag.jpg\" {$size[3]}>"; 
?> 

<?php 
$size = getimagesize ($filename); 
$fp=fopen($filename, "rb"); 
if ($size && $fp) { 
  header("Content-type: {$size['mime']}"); 
  fpassthru($fp); 
  exit; 
} else { 
  // error 
} 
?> 

/* APP Info (embedded text information) */ 
<?php 
$size = getimagesize ("testimg.jpg",&$info); 
if (isset ($info["APP13"])) { 
    $iptc = iptcparse ($info["APP13"]); 
    var_dump ($iptc);
