I've noticed that your using c:\ in your image path. this is not a good
idea, you should use your website's paths. Personally, I like to use
reletive paths such as ../ and ../../ etc...
Also, I've noticed that your using the image name as the alt tag.. this
will give you 1.jpg 2.jpg ... I'd probably leave the alt tag blank or
give it a text message.
finally, their is a method of changing the random images and keeping
your original image names and using the image name as a alt tag.
here is some code.
<?php
// Sample Code provided by Roger Bigras
$lnk = opendir("path2images"); //use a trailing slash /
$image_list = array();
while($file = readdir($lnk)){
if(is_file($path2images.$file)){
array_push($image_list,$path2images.file);
}
}
$random = mt_rand(0, ($image_list)-1);
$alt = basename($image_list[$random]);
$use = $image_list[$random];
echo "<img src='$use' alt='$alt'>";
?>
