Rinominare immagini in upload

Ho creato questo script che permette di fare il ridimensionamento e l'upload di foto, ora vorrei accodare al nome della foto caricata una stringa del tipo "NOMEFOTO**-small**.jpg" però non riesco a capire come fare, mi potete aiutare.

Questo è il codice:

[php]
<?php ini_set("memory_limit", "200000000"); // for large images so that we do not get "Allowed memory exhausted"?>
<?php
// upload the file
if ((isset($_POST["submitted_form"])) && ($_POST["submitted_form"] == "image_upload_form")) {
// file needs to be jpg,gif,bmp,x-png and 4 MB max
if (($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg" || $_FILES["image_upload_box"]["type"] == "image/gif" || $_FILES["image_upload_box"]["type"] == "image/x-png") && ($_FILES["image_upload_box"] < 4000000))
{
// if uploaded image was JPG/JPEG
if($_FILES["image_upload_box"]["type"] == "image/jpeg" || $_FILES["image_upload_box"]["type"] == "image/pjpeg"){
$image_source = imagecreatefromjpeg($_FILES["image_upload_box"]["tmp_name"]);
}
// if uploaded image was GIF
if($_FILES["image_upload_box"]["type"] == "image/gif"){
$image_source = imagecreatefromgif($_FILES["image_upload_box"]["tmp_name"]);
}
// BMP doesn't seem to be supported so remove it form above image type test (reject bmps)
// if uploaded image was BMP
if($_FILES["image_upload_box"]["type"] == "image/bmp"){
$image_source = imagecreatefromwbmp($_FILES["image_upload_box"]["tmp_name"]);
}
// if uploaded image was PNG
if($_FILES["image_upload_box"]["type"] == "image/x-png"){
$image_source = imagecreatefrompng($_FILES["image_upload_box"]["tmp_name"]);
}
$remote_file = "foto/".$_FILES["image_upload_box"]["name"];
imagejpeg($image_source,$remote_file,80);
chmod($remote_file,0644);
$new_w = 120;
$new_h = 120;
$orig_w = imagesx($image_source);
$orig_h = imagesy($image_source);

$w_ratio = ($new_w / $orig_w);
$h_ratio = ($new_h / $orig_h);
// PAESAGGIO
if ($orig_w > $orig_h ) {
$crop_w = round($orig_w * $h_ratio);
$crop_h = $new_h;
$x = ($orig_w - $orig_h) / 2;

// RITRATTO
} elseif ($orig_w < $orig_h ) {
$crop_h = round($orig_h * $w_ratio);
$crop_w = $new_w;
$y = ($orig_h - $orig_w) /2;
// QUADRATO
} else {
$crop_w = $new_w;
$crop_h = $new_h;
}
$new_image = imagecreatetruecolor($new_w,$new_h);
$image_source = imagecreatefromjpeg($remote_file);
imagecopyresampled($new_image, $image_source, 0, 0, $x, $y, $crop_w, $crop_h, $orig_w, $orig_h);
imagejpeg($new_image,$remote_file,80);
imagedestroy($new_image);
imagedestroy($image_source);

header("Location: submit.php?upload_message=image uploaded&upload_message_type=success&show_image=".$_FILES["image_upload_box"]["name"]);
exit;
}
else{
header("Location: submit.php?upload_message=make sure the file is jpg, gif or png and that is smaller than 4MB&upload_message_type=error");
exit;
}
}
?>

Ciao DARKF3D3,

devi modificare il nome nel primo parametro della funzione imagecopyresampled.

darkf3d3

Non credo di aver capito bene come fare, prima della funzione imagejpeg ho provato a far assumere alla variabile $new_image una scringa di 4 caratteri però non funziona.

Quello che vorrei riuscire a fare è salvare la stessa immagine 2 vole, una con il nome originale e una con il nome modificato, però ci riesco.

Qualcun'altro ha delle idee su come farlo?

Non so proprio come fare.
