Displaying random image using php

Hi
I am building a website and I want to display a random image every time the page is refreshed. Since I know php, I figured it would be easiest to do it using that language. Does anyone know how to do this?
Thanks
- Derek

 

<?php

$images = array(
    'image1.jpg',
    'image2.jpg',
    '...'
);

header('Content-Type: image/jpeg');
readfile($images[array_rand($images)]);

?>

PHP:

 

so I would just embed that code into my HTML?
wouldn't I have to use a <img src "" /> tag?

 

lets you have images at same folder where php file
img1
img2
img3
.
.
.
img50

<img src="img<? echo rand(1,50); ?>" >

PHP:

 

Copy the code that nico has given you into a file called image.php and call it from you html document using <img src="image.php" />
