Question

Im trying to create a simple image resize feature, can you tell me where i’m going wrong:

//resize image 
  $imageSrc = imagecreatefromjpeg('http://www.katsmurals.com/cms/'.$target_path);
  $width = imagesx($imageSrc);
  $height = imagesy($imageSrc);
  echo $width;
  echo $height;
   //new dimensions
   $i = $width;
   $j = $height;
   while($i > 700){
    $i = $i / 1.5;
    $j = $j / 1.5;
   }

  $image_p = imagecreatetruecolor($i, $j);
  $image = imagecreatefromjpeg('http://www.katsmurals.com/cms/'.$target_path);
  imagecopyresampled($image_p, $image, 0, 0, 0, 0, $i, $j, $width, $height);
  $newImage = $target_path.'_scaled.jpg';
  imagejpeg($image_p, $newImage, 80);

$target_path is the newly uploaded image, i want to resize it if the width is over 700.

Once this is done, a DB is updated with the information, at the moment the image is being uploaded fine, but the size seems to be exactly the same, so the resizing code isn’t working?

First argument of imagecopyresampled is resource (image), not string containing file name.
