Here's an example:
<?php
// Set $filedir to '.' if in current directory
$filedir = "/home/foobar/htdocs/test/uploads/";
$handle = opendir($filedir);
while ($filename = readdir($handle)) {
    // One way to get the file extension
    $ext = strtolower(substr(strrchr($filename, '.'),1));
    if ($ext == 'jpeg' || $ext == 'jpg') {
        // echo "<img src='$filename'>";
        $jpgs[] = $filename;
    }
}
closedir($handle);
?>
You asked for an array of jpg images, $jpgs will be an array of 
all .jpg and .jpeg images.  This of course can be expanded, you might 
want to replace:
  if ($ext == 'jpeg' || $ext == 'jpg') {
With:
  $goodtypes = array('gif', 'jpg', 'png', 'jpeg', 'bmp');
  if (in_array($ext, $goodtypes)) {
Makes it easy to add/manage additional types.  Uncomment the echo 
statement to echo it out immediatly, modify according to needs.
