I would start off by creating a recursive function:

function recurseDir ($dir) {

    // open the provided directory
    if ($handle = opendir($_SERVER['DOCUMENT_ROOT'].$dir)) {

        // we dont want the directory we are in or the parent directory
        if ($entry !== "." && $entry !== "..") {

            // recursively call the function, if we find a directory
            if (is_dir($_SERVER['DOCUMENT_ROOT'].$dir.$entry)) {

                recurseDir($dir.$entry);
            }
            else {  

                // else we dont find a directory, in which case we have a file                          
                // now we can output anything we want here for each file
                // in your case we want to output all the images with the path under it
                echo "<img src='".$dir.$entry."'>";
                echo "<div><a href='".$dir.$entry."'>".$dir.$entry."</a></div>";
            }
        }
    }
}

The $dir param needs to be in the following format: "/path/" or "/path/to/files/"

Basically, just don't include the server root, because i have already done that below using $_SERVER['DOCUMENT_ROOT'].

So, in the end just call the recurseDir function we just made in your code once, and it will traverse any sub folders and output the image with the link under it.

$dir = "/etc/php5/";

// Open a known directory, and proceed to read its contents

if (is_dir($dir)) {
    if ($dh = opendir($dir)) {
        while (($file = readdir($dh)) !== false) {
            echo "filename: $file : filetype: " . filetype($dir . $file) . "\n";
        }
        closedir($dh);
    }
}

<?php 
//define directory
$dir = "images/";
//open directory
if ($opendir = opendir($dir)){
//read directory
 while(($file = readdir($opendir))!= FALSE ){
  if($file!="." && $file!= ".."){
   echo "<img src='$dir/$file' width='80' height='90'><br />";
  }
 }
} 
?>

Hi you can use DirectoryIterator

try {
    $dir = './';
    /* @var $Item DirectoryIterator */
    foreach (new DirectoryIterator($dir) as $Item) {
        if($Item->isFile()) {
            echo $Item->getFilename() . "\n";
        }
    }
} catch (Exception $e) {
    echo 'No files Found!<br />';
}

If you want to pass directories recursively: http://php.net/manual/en/class.recursivedirectoryiterator.php

You could also try the glob function:

$path = '/your/path/';
$pattern = '*.{gif,jpg,jpeg,png}';

$images = glob($path . $pattern, GLOB_BRACE);

print_r($images);

I use something along the lines of:

if ($dir = dir('images'))
{       
    while(false !== ($file = $dir->read()))
    {
        if (!is_dir($file) && $file !== '.' && $file !== '..' && (substr($file, -3) === 'jpg' || substr($file, -3) === 'png' || substr($file, -3) === 'gif'))
        {
            // do stuff with the images
        }
    }
}
else { echo "Could not open directory"; }

You could as others have suggested check every file in the dir, or you could use glob to identify files based on extension.

if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            echo "$file\n";
        }
    }
    closedir($handle);
}

use readdir

You'll want to use the scandir function to walk the list of files in the directory.
