looking for php random image plus random alt from folder script

[Marquis]

Hi all

I'm looking for a php script where I can load and include random images from a specific folder plus random alt descriptions from a specific folder as .txt file for every image. Description must not be associated to a specific image, just random. As I want to include multiple random images with alt descriptions on a page, it was very good if there was a solution with a good randomizing or a function to exclude duplicate includes. Is it possible? I just a found a simple script which does the work with images, but can't figure out how to include the random textfiles as alt descriptions.

any help is much appreciated

$folder = "./images/random/";
$imagetyp = array("gif","jpg","png","bmp");
$source = dir($folder);
$imagename = array();
while($file = $source->read()){$format = substr(strrchr($file,".") ,1);
if (in_array($format,$imagetyp)){$imagename[] = $file;}}
$quelle->close();
srand((double) microtime()*10000000);
$typ = array_rand($imagename);
echo "<div align='center'><img src='$folder/$imagename[$typ]' alt='' /></div>";
