What are the potential pitfalls of not correctly activating JPEG support in PHP?

If JPEG support is not correctly activated in PHP, it can lead to errors when trying to manipulate JPEG images using PHP functions such as imagecreatefromjpeg(). To solve this issue, you need to ensure that the GD extension is properly installed and enabled in your PHP configuration. 

// Check if GD extension with JPEG support is enabled
if (!extension_loaded('gd') || !function_exists('imagecreatefromjpeg')) {
    die('GD extension with JPEG support is not enabled');
}
