PHP GLOB skips the first image in each folder - php

Question

I am trying to understand why GLOB is skipping the first image in whatever folder I direct it too. I work around it by placing a dummy image named so it is listed first but I would like to solve this irk in a more efficient way. Here is my code.
<?php
// This retrieves images from a selected folder - anchor with a data-xx-xx attribute
// via jQuery - click - the data-xx-x value is put into a hidden field : foldpath
// It all works fine BUT, it always fails to return the first image in a folder
// I get around it by placing within each folder a dummy image called aa.jpg
// which hopefully will always be the first image but it is not really a
// satisfactory solution.
if($_POST && isset($_POST["foldsub"]) && isset($_POST["foldpath"]) ){
// hidden field $_POST["foldpath"];
//A typical path might be :
// ../images/products/CLIENTS_images/bridal_whatnots/bridal_belts
//the ../ prefix is reoved via php when the page is displayed and replaced by DIR
// for testing between admin folders and the main root folders I use the relative paths.
$fp = $_POST["foldpath"];
$files = glob($fp ."/" ."*.*");
//this is a pop up page which needs to stay open after the selection has been made
echo "<script> $(\"#imgstuff\").css({\"display\":\"block\"});</script>";
//the form closed on whgen the close x is selected
}else
{
//default
$files = glob("../images/bannerImgs/*.*");
}
for ($i=0; $i<count($files); $i++)
{
$image = $files[$i];
$supported_file = array(
'jpg',
'jpeg',
'png'
);
$ext = strtolower(pathinfo($image, PATHINFO_EXTENSION));
if (in_array($ext, $supported_file)) {
// print $image ."<br />";
$path = $image;
$path1 = DIR;
if (strpos($path, $path1) !== false) {
$path2 = $path;
}else{
$path2 = str_replace('../', '', $path);
$path2 = $path1.$path2;
}
$fn = basename($path);
$fn = basename($path, PATHINFO_EXTENSION);
if($fn!="aa.jpg"){
echo '<p class="imgdet">';
// echo '<span class="imglongpath">' . $path2 .'</span>';
echo '<img src="'.$image .'" alt="Random image" />';
echo '<span class="imgname">' . $fn .'</span>';
// echo '<span class="imgmesg">Now click Confirm / Set Choice</span>';
// "<br /><br />";
echo "</p>";
}
} else {
continue;
}
}
?>
