I know what jpeg compression is, what's your point?

Hello, what's the correct use of GD library to compress JPG images please? I am using this upload script with TinyMCE. See below : I have this snippet but it doesn't compress the image: // Accept upload if there was no origin, or if it is an accepted origin // If image is JPEG compress with GD library $filetowrite = $imageFolder . $temp['name']; if (in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("jpg", "jpeg"))) { imagejpeg($temp['tmp_name'], $filetowrite, 75); } else { move_uploaded_file($temp['tmp_name'], $filetowrite); } <?php $accepted_origins = array("http://localhost", "http://127.0.0.1", "http://192.168.1.1", "http://example.com"); $month = strtolower(date('M')); $year = date('Y'); $newspath = "img/news/"; if (!is_dir("$newspath/$year/$month")) { mkdir("$newspath/$year/$month", 0777, true); } $imageFolder = "$newspath/$year/$month/"; reset ($_FILES); $temp = current($_FILES); if (is_uploaded_file($temp['tmp_name'])){ if (isset($_SERVER['HTTP_ORIGIN'])) { // same-origin requests won't set an origin. If the origin is set, it must be valid. if (in_array($_SERVER['HTTP_ORIGIN'], $accepted_origins)) { header('Access-Control-Allow-Origin: ' . $_SERVER['HTTP_ORIGIN']); } else { header("HTTP/1.1 403 Origin Denied"); return; } } /* If your script needs to receive cookies, set images_upload_credentials : true in the configuration and enable the following two headers. */ // header('Access-Control-Allow-Credentials: true'); // header('P3P: CP="There is no P3P policy."'); // Sanitize input if (preg_match("/([^\w\s\d\-_~,;:\[\]\(\).])|([\.]{2,})/", $temp['name'])) { header("HTTP/1.1 400 Invalid file name."); return; } // Verify extension if (!in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("gif", "jpg", "jpeg", "png"))) { header("HTTP/1.1 400 Invalid extension."); return; } // Accept upload if there was no origin, or if it is an accepted origin // If image is JPEG compress with GD library $filetowrite = $imageFolder . $temp['name']; if (in_array(strtolower(pathinfo($temp['name'], PATHINFO_EXTENSION)), array("jpg", "jpeg"))) { imagejpeg($temp['tmp_name'], $filetowrite, 75); } else { move_uploaded_file($temp['tmp_name'], $filetowrite); } // Respond to the successful upload with JSON. // Use a location key to specify the path to the saved image resource. // { location : '/your/uploaded/image/file'} // echo json_encode(array('location' => $filetowrite)); $passpath = $year.'/'.$month.'/'.$temp['name']; echo json_encode(array('location' => $passpath)); } else { // Notify editor that the upload failed header("HTTP/1.1 500 Server Error"); } ?>
