Using the GD2 Library in php to create images cannot be displayed in the browser

Using the GD2 Library in php to create images cannot be displayed in the browser. I just learned PHP and cannot display images in the browser when using the GD2 library to create images, there is only one icon representing the image. my code is as follows: & lt ;? Php & nbsp; header ("content-type: image/gif"); $ images created using the GD2 Library in php cannot be displayed in the browser
Shortly after I first learned PHP, when I used the GD2 library to create an image, I couldn't display the image in the browser. there was only one icon representing the image. my code is as follows:
Header ("content-type: image/gif ");
$ Image = imagecreate (, 80 );
$ Bg = imagecolorallocate ($ image, 220, 40,120 );
Imagegif ($ image );
?>
It should be okay, but it cannot be displayed. thank you for your guidance! Thank you!
