How to create a radom image displayer.

Hi guys. I have a folder with a load of images in, all of which are named diffrently. They are all .jpg however so that makes things a little bit easier I was just wondering how I would go about setting up a peice of php code that will pick one of these images and display it.

Basicaly a random image generator I have googled it but all the tutorials seem to only work if you name the images 1.jpg 2.jpg etc any help would be great.

$pictures=glob('images/*.jpg');
echo $pictures[rand(0,count($pictures)-1)];

Another way:
[code]<?php
$pictures = glob('images/*.jpg');
echo '<img src="' . $pictures[array_rand($pictures)] . '">';
?>[/code]

ok I have tried both methods and for the first one it prints out '; ?> while the second example just displays blank, any ideas?  Heres what ive done

<?php
$pictures=glob('PrizeGiving/thumbnails/*.jpg');
echo $pictures[rand(0,count($pictures)-1)];
?>

try print_r($pictures); is the array got anything in it?

First, you're declaring a relative path from the current file, so make sure your script is sitting in the folder containing the [i]PrizeGiving[/i] directory. Once you've done that, try printing out your glob() results and see if it's actually picked up your image names:
[code]
<?php
// Make sure that your images are named appropriately and that you have
// your case correct for your full path
$pictures = glob("PrizeGiving/thumbnails/*.jpg");
print_r($pictures);
?>
[/code]

If the above code, does indeed collect all your image names, here's another alternative to get a random image:
[code]
<?php
$pictures = glob("PrizeGiving/thumbnails/*.jpg");
shuffle($pictures);
echo "<img src=\"{$pictures[0]}\" />";
?>
[/code]

Good luck!
