<strong>Notes:</strong><br />
The image will not be resized to this exact size; it will be scalled down so that neider width or height is larger than specified.<br />
When uploading this script make sure you have a directory called "image_files" next to it and make that directory writable, permissions 777.<br />
After you uploaded images and made tests on our server please <a href="delete_all_images.php">delete all uploaded images </a> :)<br />
