Code:
$dir = '/home/path/to/randomimage';
# This is the web path to directory that holds the images
$weburl = 'http://www.yoursite.com/randomimage';
########################################################
# The script
########################################################
opendir(DIR, $dir) || die "$!";
while ($_ = readdir DIR)
{
if(-f "$dir/$_"){
push(@dir, $_);
}
}
closedir(DIR);
$count = scalar @dir;
$i = int(rand( $count ));
print "Content-type: text/html\n\n";
print "<img src=\"$weburl/$dir[$i]\">";
This is just copied from a script i wrote a really long time ago that does exactly what you want.
