php random image

[john1991]

Hi all,

I am trying to generate a random image form file within a list item.

I am missing something but trying to figure it out, here is my code I am working with:

<!-- bg img -->
<?php
$images = array(

  array('file1'    => 'bg',
        'caption' => ''),

  array('file2'    => 'bg2',
        'caption' => ''),

  );
$i = rand(0, count($images)-1);
$selectedImage = "img/{$images[$i]['file1'] ['file2']}.jpg";
$caption = $images[$i]['caption'];
if (file_exists($selectedImage) && is_readable($selectedImage)) {
  $imageSize = getimagesize($selectedImage);
  }
?>
<div class="jbgallery">

 <ul>
  <li><a href="<?php echo $selectedImage; ?>">1</a></li>
  <li><a href="<?php echo $selectedImage; ?>">2</a></li>
 </ul>

</div>
<!-- end -->

Thank you for any help and suggestions.

Are you trying to make the list of images in a random order? Or one random image the same for every list item.
