If the script should resize and save thumb I use this simple code, I made a couple corrections from last one and added the possibility to resize to a max HEIGHT:
<?php
/**
* Make thumbs from JPEG, PNG, GIF source file
*
* $tmpname = $_FILES['source']['tmp_name'];
* $size - max width size
* $save_dir - destination folder
* $save_name - tnumb new name
* $maxisheight - is max for width (if not is for height)
*

/*/ // And now how using this function fast:
if ($_POST[pic])
{
$tmpname = $_FILES['pic']['tmp_name'];
@img_resize( $tmpname , 600 , "../album" , "album_".$id.".jpg");
@img_resize( $tmpname , 120 , "../album" , "album_".$id."_small.jpg");
@img_resize( $tmpname , 60 , "../album" , "album_".$id."_maxheight.jpg", 1);
}
else
echo "No Images uploaded via POST";
/**/
function img_resize( $tmpname, $size, $save_dir, $save_name, $maxisheight = 0 )
{
$save_dir .= ( substr($save_dir,-1) != "/") ? "/" : "";
$gis = getimagesize($tmpname);
$type = $gis[2];
switch($type)
{
case "1": $imorig = imagecreatefromgif($tmpname); break;
case "2": $imorig = imagecreatefromjpeg($tmpname);break;
case "3": $imorig = imagecreatefrompng($tmpname); break;
default: $imorig = imagecreatefromjpeg($tmpname);
}
$x = imagesx($imorig);
$y = imagesy($imorig);
$woh = (!$maxisheight)? $gis[0] : $gis[1] ;
if($woh <= $size)
{
$aw = $x;
$ah = $y;
}
else
{
if(!$maxisheight){
$aw = $size;
$ah = $size * $y / $x;
} else {
$aw = $size * $x / $y;
$ah = $size;
}
}
$im = imagecreatetruecolor($aw,$ah);
if (imagecopyresampled($im,$imorig , 0,0,0,0,$aw,$ah,$x,$y))
if (imagejpeg($im, $save_dir.$save_name))
