<input type="file" name="file" id="file"><br>

</form>

</body>
</html>
<?php
$allowedExts = array("gif", "jpeg", "jpg", "png");
$temp = explode(".", $_FILES["file"]["name"]);
$extension = end($temp);

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/jpg")
|| ($_FILES["file"]["type"] == "image/pjpeg")
|| ($_FILES["file"]["type"] == "image/x-png")
|| ($_FILES["file"]["type"] == "image/png"))
&& in_array($extension, $allowedExts)) {
if ($_FILES["file"]["error"] > 0) {
echo "Return Code: " . $_FILES["file"]["error"] . "<br>";
} else {
echo "Upload: " . $_FILES["file"]["name"] . "<br>";
echo "Type: " . $_FILES["file"]["type"] . "<br>";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br>";
if (file_exists("images/" . $_FILES["file"]["name"])) {
echo $_FILES["file"]["name"] . " already exists. ";
} else {
move_uploaded_file($_FILES["file"]["tmp_name"],
"images/" . $_FILES["file"]["name"]);
$filename = "images/" . $_FILES["file"]["name"];
$image = $_FILES["file"]["name"];


$im = new Imagick($image);
$im->setResolution(144,144);
$im->readImage($image);

$percent = 0.5;

list($width, $height) = getimagesize($filename);

$newwidth = $width * $percent;
$newheight = $height * $percent;

// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);

// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
$path = "images/upload/T".$image;
imagejpeg($thumb,$path);
imagedestroy($thumb);

//thumb
$target_width = $width * 1;
$target_height = $height * 1;
// Load
$thumb = imagecreatetruecolor($target_width, $target_height);
$source = imagecreatefromjpeg($filename);
imagecopyresized($thumb, $source, 0, 0, 0, 0, $target_width, $target_height, $width, $height);
$path = "images/thumb/U".$image;
imagejpeg($thumb,$path);
imagedestroy($thumb);

}
}
} else {
echo "Invalid file";
}
?>

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Putting aside the fact that you give the wrong filename to imagick, which will throw an exception when it can't find the file, you don't actually USE imagick to do anything. All the work is done by GD.
