dag mensen ik zit met een probleem. als ik een te groot plaatje heb wil ik em verkleinen en in een variabele weer terug krijgen. het is tot dusver gelukt dat ik de nieuwe image "bouw". alleen hier loop ik op vast:
wat moet ik bij de "imagegif" invullen?
voor een beter overzicht hier de hele pagina. zie lijn 130
Alvast Bedankt
PHP:
imagecopyresized( $thumb, $img, 0, 0, 0, 0, $newwidth, $newheight, $image_width, $image_height );
imagegif( $thumb, $_FILES['thumb_image']['tmp_name'] );voor een beter overzicht hier de hele pagina. zie lijn 130
