falls es für nachfolgende interessant ist hier der komplette code:
Bild verkleinern in 700x525 (kann verändert werden), speichern, Wasserzeichen einfügen.
upload.php:
<?php
session_start();
if( isset($_POST['submit']) ) {
include('SimpleImage.php');
$image = new SimpleImage();
$image->load($_FILES['uploaded_image']['tmp_name']);
$image->resize (700, 525);
$image->save('bilder/Bild_01.JPG');
header('Content-type: image/jpeg');
//Bilder in Variablen Laden
$Grafik = ImageCreateFromJPEG("bilder/Bild_01.JPG");
//Wasserzeichen erstellen
$im = imagecreate (305, 30);
$black = ImageColorAllocate ($im, 0, 0, 0);
$white = ImageColorAllocate ($im, 255, 255, 255);
//ImageTTFText ($im, 20, 0, 10, 20, $white, "XFILES.TTF",
ImageTTFText ($im, 15, 0, 10, 22, $white, $_SERVER['DOCUMENT_ROOT']."/upload_bilder/ARIAL.TTF",
"© 123.de - 2010");
//Bearbeitung
ImageCopy($Grafik, $im,
imagesx($Grafik)-imagesx($im),
imagesy($Grafik)-imagesy($im), 0, 0,
imagesx($im),
imagesy($im));
//Bilder ausgabe
imagejpeg($Grafik);
//Bild Speichern
imagejpeg($Grafik, "bilder/Bild_01.JPG");
