snippet voor foto resize - draai issue

dat komt omdat in de EXIF een rotation value is ingesteld.

lees de comments eens op php.net

Daar zie je staan:

<?php
$image = imagecreatefromstring(file_get_contents($_FILES['image_upload']['tmp_name']));
$exif = exif_read_data($_FILES['image_upload']['tmp_name']);
if(!empty($exif['Orientation'])) {
    switch($exif['Orientation']) {
        case 8:
            $image = imagerotate($image,90,0);
            break;
        case 3:
            $image = imagerotate($image,180,0);
            break;
        case 6:
            $image = imagerotate($image,-90,0);
            break;
    }
}
// $image now contains a resource with the image oriented correctly
?>

hey Randy ok merci

de foto staat nu op de juiste richting in de upload folder
maar de foto zelf op de site is niet mee gedraaid staat nog in originele setting
(dus stond de foto in portret in verkenner en ik draai hem naar landscape -> laad ik deze op->
in de folder op de server staat de foto als landscape maar op de website staat hij nog steeds in portret mode)
