that file has nothing but functions. where is the code that utilizes the functions?

[areuban]

i tried this to utlise the function. im a real novice, learning each day <img src="crop.php?x=10&y=20&w=30&h=40&src=templates/new/images/site_header.jpg">

that will not utilize the function. you need to write a PHP file called crop.php, which then accepts the values for x, y, etc. then utilizes those functions to do what you want.

<?php

$w=$_GET['w'];

$h=isset($_GET['h'])?$_GET['h']:$w;   

$x=isset($_GET['x'])?$_GET['x']:0;   

$y=isset($_GET['y'])?$_GET['y']:0; 

$filename=$_GET['src'];

header('Content-type: image/jpg');

header('Content-Disposition: attachment; filename='.$src);

$image = imagecreatefromjpeg($filename);

$crop = imagecreatetruecolor($w,$h);

imagecopy ( $crop, $image, 0, 0, $x, $y, $w, $h );

imagejpeg($crop);

?>

UPDATE: ok this is the script i have now (SimpleImage.php) then i created this :<?php

  if( isset($_POST['submit']) ) {

      include('SimpleImage.php');

      $image = new SimpleImage();

      $image->load($_FILES['uploaded_image']['tmp_name']);

      $image->resizeToWidth(150);

      $image->output();

  } else {

?>

 

  <form action="upload.php" method="post" enctype="multipart/form-data">

      <input type="file" name="uploaded_image" />

      <input type="submit" name="submit" value="Upload" />

  </form>

 

How can i then output the resulting image as part of an html file? after it has resized and saved it? please help

after you have the file saved, just put it in html like any other image file:

 

echo "<img src='" . "/path/to/image" . "'>";

thanks, when i save the file, how can i make it automatically save it as the originalfile with a thumb suffix... eg. jack.jpg and after it is resized, save it as jackthumb.jpg?

[areuban]

and after the upload form can i make it automatically display the resized image on the same page?
