Automatically list images in a directory with PHP

Sometimes I want to lob some images into a directory to be viewed online for review.

There is a way of doing this using glob which is a function in PHP that searches for path names matching patterns according to specified rules.

<?php
echo('<style type="text/css">
img {
 margin:3px;
 padding: 7px;
 border: 1px solid #aaa;
 background: #eee;
 display: inline-block;
}
p {
}
</style>');
//specify the directory
$latestfiles = glob("images/*.*");
echo('<h1>Latest</h1>');
for ($i=1; $i<count($latestfiles); $i++) {
 $image = $latestfiles[$i];
 echo '<p><img src="'.$image .'" alt="Random image"/>'."<br/>URL: <a href=\"".$image."\">".$image.'</a></p>';
?>

This codes allows me to show all files within a directory and can even be expanded to make a basic file manager.
