PHP Image Resize

[dezkit]

Hey, I have this code:

  if ($_FILES["file"]["error"] > 0)
    {
    echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
    } else {
    echo "<font color=\"red\" size=\"+1\">Image has been uploaded!</font><br><br>";
   if (file_exists("./uploads/" . $_FILES["file"]["name"]))
      {
      echo $_FILES["file"]["name"] . " already exists. ";
      } else {
     $filename = $_FILES["file"]["name"];
      move_uploaded_file($_FILES["file"]["tmp_name"], $target);
      $thumbn = $sein . "th-" . $fale;
      cropImage(83, 60, "$target", "$ext", "$thumbn");
      include("config.php");
      $thumbnailss = "th-".$fale;
      mysql_query("INSERT INTO gallery (thumb_url, full_url) VALUES('$thumbnailss', '$fale' ) ") or die(mysql_error());  
      }
    }

 

How do i make it so that the file is going to be re sized half its size? There are no tutorials on this, i have searched google, thanks guys.

I have found this code:

<?php
// File and new size
$filename = 'test.jpg';
$percent = 0.5;

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

// Get new sizes
list($width, $height) = getimagesize($filename);
$newwidth = $width * $percent;
$newheight = $height * $percent;

// Load
$thumb = imagecreatetruecolor($newwidth, $newheight);
$source = imagecreatefromjpeg($filename);

// Resize
imagecopyresized($thumb, $source, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);

// Output
imagejpeg($thumb);
?>

 

But how do i implement that code into my code? Thanks

cropImage()? Are you using ImageMagick?

cropImage()? Are you using ImageMagick?

 

That's a function I created to make a thumbnail of the uploaded file, but this is what i want

 

user uploads an image (done)

uploaded image gets half sized and saved to /uploads/ (getting help from you guys!)

using my function cropImage() to crop the uploaded image and save the image to /uploads/ (done)

I'm sorry for not understanding but when you say half sized, do you literally mean half of the bytes or half the resolution?  If it's resolution, just use the code you found without the header() line, and using a second parameter for imagejpeg() (http://www.php.net/imagejpeg if you haven't used this before).

 

If you need more help, I guess I could whip you up some code.

Half resolution, but i don't really know how to do it, i can't mess with the code or i can ruin it.
