|images to that folder to have them randomly displayed. |
| |
|You can also edit the variable $pattern if you know what |
|you are doing. |
| |
|To display the random image on your web page, you can |
|either copy and paste all of this code into the page where |
|you want it or you can include it by putting in the |
|following code into the page where you want the image: |
|<?php include "yourfile.php"; ?> |

$dir=opendir("/home/you/public_html/folder/");
//This is the directory route to the folder
$directory="";
//This is a relative link to the directory if it is not in the same directory as the file you are displaying the images on

$pattern="\.(gif|jpg|jpeg|png|bmp|swf)$";
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]>";
?>
