With the following code, my browser is returning 'image not created or saved'. I assure you the location of the image exists. So the line within the if statement is returning false for some reason, and yes GD is installed. Any ideas?

if ($img = @imagecreatefromjpeg("/var/www/images/upload/1/1.jpg")) {

            $image_width = imagesx($img);
            $image_height = imagesy($img);
            $target_width = 150;
            $target_height = 150;

            if ($image_width > $image_height) {

                $percentage = ($target_width / $image_width);

            } else {

                $percentage = ($target_height / $image_height);

            }

            $new_image_width = round($image_width * $percentage);
            $new_image_height = round($image_height * $percentage);

            $imgResized = imagecreatetruecolor($new_image_width, $new_image_height);
            imagecopyresampled($imgResized, $img, 0, 0, 0, 0, $new_image_width, $new_image_height, $image_width, $image_height);

            imagejpeg($imgResized, $this->path, 100);
            imagedestroy($img);
            imagedestroy($imgResized);
            $this->storeThumbnailLocation();

        } else {

            die ("image was not created or saved");

        }
