Imagejped() function problems

[Dan911]

I created a script that resizes images, and saves them to the server. Everything works, but i get a white screen instead of th original web page, what is up?

Here is the code 🙂

		  

          //load image from server
          $image = open_image($_SERVER['DOCUMENT_ROOT'].'/'.$_POST['imageresize']);

      //see it it is there
      if ($image === false) { die ('Unable to open image' . $_SERVER['DOCUMENT_ROOT'].'/'.$_POST['imageresize']); }

      // Get original width and height
      $width = imagesx($image);
      $height = imagesy($image);


      // Set a new width, and calculate new height
      $new_width = 200;
      $new_height = $height * ($new_width/$width);

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

      // Display resized image and save it(hoepfully)
	  header('Content-Type: image/jpeg')
	  imagejpeg($image_resized,'../images/resizedimage.jpg');
	  imagedestroy($image_resized); 





      die();

      function open_image ($file)
      {
               # JPEG:
               $im = @imagecreatefromjpeg($file);
               if ($im !== false) { return $im; }

                # GIF:
                 $im = @imagecreatefromgif($file);
                 if ($im !== false) { return $im; }

                 # PNG:
                 $im = @imagecreatefrompng($file);
                 if ($im !== false) { return $im; }

                 # GD File:
                 $im = @imagecreatefromgd($file);
                 if ($im !== false) { return $im; }

                 # GD2 File:
                 $im = @imagecreatefromgd2($file);
                 if ($im !== false) { return $im; }

                 # WBMP:
                 $im = @imagecreatefromwbmp($file);
                 if ($im !== false) { return $im; }

                 # XBM:
                 $im = @imagecreatefromxbm($file);
                 if ($im !== false) { return $im; }

                 # XPM:
                 $im = @imagecreatefromxpm($file);
                 if ($im !== false) { return $im; }

                 # Try and load from string:
                 $im = @imagecreatefromstring(file_get_contents($file));
                 if ($im !== false) { return $im; }

                 return false;
       }

There's an error somewhere that you're not seeing. Add the following to the top of your script (right after the opening '<?php' tag)...

error_reporting(E_ALL);

That should provide you some information to go on.

Thanks you for your help, but where would the errors print out, in a a log file? cause none are shown on the page

I don't see anything in your code that would cause any output to the screen. In fact you have a die() function running at the end. What are you expecting to see? Is there more code we should look at?
