I actually just hacked one up. This hooks into a Gallery
(gallery.sourceforge.org) album directory and picks out files with the
string, "sized", in their filenames. It then creates an array such that
the more recent pictures get more entries in the array which means when I
pick a random image I am more likely to see a recent image.
<?
$base = '/some/dir/albums/name';
$dir = opendir($base);
$chance=0;
$i=0;
while($entry=readdir($dir)) {
if(strstr($entry,'sized')) {
if(!($i%3)) $chance++;
for($j=0; $j<$chance; $j++) {
$pics[]=$entry;
}
$i++;
}
}
closedir($dir);
$max = count($pics);
$val = rand(0,$max-1);
Header("Content-Type: image/jpeg");
$size = filesize($base.'/'.$pics[$val]);
Header("Content-Length: $size");
Header("Expires: Thu, 19 Nov 1981 08:52:00 GMT");
Header("Cache-Control: no-store, no-cache, must-revalidate, post-check=0,
pre-check=0");
Header("Pragma: no-cache");
readfile($base.'/'.$pics[$val]);
?>
