It is working so far.. Please find the script I am using below, the
batch process also makes the filenames unique and writes their names to
a database. Thanks for your help!
<?php
require 'inc/db_connect.php';
$imagefolder='.';
$thumbsfolder='.';
$pics=directory($imagefolder,"jpg,JPG,JPEG,jpeg,png,PNG");
$pics=ditchtn($pics,"tn_");
if ($pics[0]!="")
{
foreach ($pics as $p)
{
createthumb($p,"tn_".$p,150,150);
}
}
/*
Function ditchtn($arr,$thumbname)
filters out thumbnails
*/
function ditchtn($arr,$thumbname)
{
foreach ($arr as $item)
{
if (!preg_match("/^".$thumbname."/",$item)){$tmparr[]=$item;}
}
return $tmparr;

/*
Function createthumb($name,$filename,$new_w,$new_h)

variables:
$name Original filename
$filename Filename of the resized image
$new_w width of resized image
$new_h height of resized image
*/
function createthumb($name,$filename,$new_w,$new_h)
{
$system=explode(".",$name);
if
(preg_match("/jpg|jpeg/",$system[1])){$src_img=imagecreatefromjpeg($name);}

(preg_match("/png/",$system[1])){$src_img=imagecreatefrompng($name);}
$old_x=imageSX($src_img);
$old_y=imageSY($src_img);
if ($old_x > $old_y)
{
$thumb_w=$new_w;
$thumb_h=$old_y*($new_h/$old_x);
}
