How can error handling be improved in the code snippet provided to troubleshoot the issue with thumbnail creation?

The issue with the code snippet provided for thumbnail creation is that it lacks proper error handling, which can lead to unexpected behavior or failures. To improve error handling, we can use try-catch blocks to catch any exceptions that may occur during the image processing and provide appropriate error messages or fallback options. 

try {
    $image = imagecreatefromjpeg($img_path);
    if ($image === false) {
        throw new Exception('Failed to create image from JPEG');
    }

    $thumbnail = imagescale($image, $thumb_width, $thumb_height);
    if ($thumbnail === false) {
        throw new Exception('Failed to create thumbnail');
    }

    imagejpeg($thumbnail, $thumb_path);
    imagedestroy($thumbnail);
    imagedestroy($image);
} catch (Exception $e) {
    echo 'Error creating thumbnail: ' . $e->getMessage();
}
