Answer 1

$imagePattern = "/\.(jpg|jpeg|png|gif|bmp|tiff)$/";
$directory = ".";

if (($handle = opendir($directory)) != false) {
    while (($file = readdir($handle)) != false) {
        $filename = "$directory/$file";
        if (strtotime("-24 hours") <= filemtime($filename) && preg_match($imagePattern, $filename)) {
            unlink($filename);
        }
    }

    closedir($handle);
}

If you're on *nix, punt it off to the shell and find:

shell_exec('find /path/to/your/directory -mtime +0 -exec rm -f {} \;');

combination of:

An alternate solution would be to use a naming convention that includes a unix timestamp if you have control over that.

shell_exec('find /path/to/files* -mtime +1 -exec rm {} \;');
