Hi there guys. I've been a reader on this site for quite a bit, but this is my first post. This site has already helped me through so many problems!!

I am somewhat of a newbie to site building, but slowly and surely, thanks to this site, I've been getting the hang of it, so I am sorry if my question sounds as if it's coming from a newbie, but it is! :)

I want a random picture to show up each time someone visits my site, or when my site gets refreshed. I have the photos saved to a folder called "randomphoto". I guess the full location would be considered "C:\Documents and Settings\default\My Documents\My Webs\mysite\randomphoto"
Currenly, I have 3 photos in the folder, 1.jpg, 2.jpg, and 3.jpg.

I was told to copy and paste the script below into where I want the random pictures to be displayed..


*/
$dir=opendir("Documents and Settings\default\My Documents\My Webs\mysite\randomphoto");
$directory="";

$pattern="\.(gif|jpg|jpeg|png|bmp|swf)$";
if(!$dir)
{
die("Failed to read directory");
}
$s=readdir($dir);
$count="0";
$image;
while($s)
{
if(ereg($pattern, $s))
{
$image[$count]=$s;
$count++;
}
$s=readdir($dir);
}
closedir($dir);

//Spit it out
$limit=count($image);
$limit--;
$randNum=rand(0,$limit);
$size=getimagesize("$directory$image[$randNum]");
echo "<br><img src=\"$directory$image[$randNum]\" $size[3]>";
?>


I got that HTML from a user on the Microsoft FrontPage forums. I stated that I wanted a random picture to be displayed from a particular folder, and I wanted each picture to be roughly 160x159.

Well upon copying and pasting that into where I want the pictures to be displayed, it just doesn't work!

Does anyone know where the problem is?

Any help would be appreciated!!
Thanks!!

Try this one. It works great for me. past it under the <head> tag. JF
