In PHP:
<?php
if(isset($_REQUEST['upload'])){
$file_name = strtolower($_FILES['files']['name']);
$uploadedfile = $_FILES['files']['tmp_name'];
$src = imagecreatefromjpeg($uploadedfile);
list($width,$height)=getimagesize($uploadedfile);
$newwidth=250;
// $newheight=250;
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);
imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);
$filename = "uploads/thumb/". $_FILES['files']['name'];
imagejpeg($tmp,$filename,3000);
$result = move_uploaded_file($_FILES['files']['tmp_name'], 'uploads/large/'.$file_name);
if($result){
echo '<p class="success"> Image uploaded and resized successfully.</p>';
} else {
echo '<p class="error"> Image can\'t upload and resized.</p>';
