If you get a red X it means the path to your images is wrong. Double check the image url.

and the php file code is

$path = 'images\randomimages';
$i = 0;
$imgDir = opendir ($path);
while ( $file = readdir( $imgDir ) )

//checks that file is an image
$file_type = strrchr( $file, "." );
$is_image = eregi( "jpg|gif",$file_type );
if ( $file != '.' && $file != '..' && $is_image )
{ $images[$i++] = $file; }
}
closedir ($imgDir);
srand( (double) microtime()*1000000 );
$image_name = $path . '/' . $images[rand( 0,sizeof( $images ) -1 )];
$imgSize = GetImageSize( $image_name );
//ends script if no images found
if ( $i == 0 )
die();
//Display the image
readfile("$image_name");
?>

leave your $path variable blank, only put a single slash in there like this

$path = '\';

problem is the script is looking for images in 'images/randomimages' while the script is already in there. So now its looking for images in 'images/randomimages/images/randomimages'.

Correct me if im wrong

That's not what the code is doing, it's selecting one random image.

Try this, you were missing a bracket somewhere. :ph34r:

<?php
//directory here (relative to script)
$path = './images\randomimages';
$i = 0;
$imgDir = opendir ($path);
$images = array();
while ( $file = readdir( $imgDir ) )
{
	//checks that file is an image
	$file_type = strrchr( $file, "." );
	$is_image = eregi( "jpg|gif",$file_type );
	
	if ( $file != '.' && $file != '..' && $is_image )
	{ 
		$images[$i++] = $file; }
	}

	closedir ($imgDir);
	srand( (double) microtime()*1000000 );
	$image_name = $path . '/' . $images[rand( 0,sizeof( $images ) -1 )];
	$imgSize = GetImageSize( $image_name );
}
//ends script if no images found
if ( $i == 0 )
{
	die();
}
else
{
	//Display the image
	readfile($image_name);
}
?>

Post if it doesn't work, I have not tested it.

I'm not sure but I think there was a directory error. Try that although i've not tested it!
