als ik gewoon een plaatje upload, zonder er iets mee te doen, doe ik zoiets als:
// origineel opslaan
$destfile = $userimagedir.$_FILES["image"]["name"];
move_uploaded_file($imagepath,$destfile);
$sql = "update machine set userimage = '" . $_FILES["image"]["name"] . "' where id = $id";
//echo $sql;
$result = mysql_query($sql);
echo mysql_error();
alleen.,,, ik wil m nu eerst bewerken en dan pas opslaan..het bewerkte plaatje staat in $image_resized..maar hoe sla ik dat plaatje vervolgen op in mijn map 'image' en de bestandsnaam in mijn database?

// Resample
$image_resized = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
$image_resized = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($image_resized, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
