upload + resize = colori sballati

[Oscurodrago]

ho fatto questo codice per gli upload nel quale deve anche fare il resize dell immagine soltanto che durante il resize la miniatura ha dei colori sballati ...

sapreste dirmi che c'e che non va bene?

function send_images($title, $date, $consol, $gameid, $img1, $img1_name, $img1_type, $img1_size, $hits, $id) {
    global $abpath, $ablink, $sizelim, $admin, $size, $EditedMessage, $prefix, $dbi, $module_name, $db, $widthprefer;
    include ('header.php');
    OpenTable();


    $result = $db->sql_query("SELECT * FROM ".$prefix."_Games_Images");
    $numresults = $db->sql_numrows($result);
	$nomeimgz = $numresults+1;



$date = date("Y-m-d", time());
$titleimg = $_POST['title'];
$consol =$_POST['consol'];
$gameid =$_POST['gameid'];

[][]
posto un immagine normale e ridimensionata non so se vi puo servire

[13manuel84]

quando crei l'immagine al posto di
$def = imagecreate($widthN, $heightN);

metti:

$def = imagecreatetruecolor($widthN, $heightN);
