maybe my solution will be helpful

at first create a folder 'images_full'
create an upload script:
CODE
<html>
<head>
<title>Upload foto</title>
</head>

<body>
<? if($img):
$date=date("Y-m-d");
copy($img,"images_full/".$img_name);
list($width,$height)=getimagesize("images_full/".$img_name);
$insert=mysql_query("insert into $tabulka(image,descript,date,width,height) values('$img_name','$_POST[obr_popis]','$date','$width','$height')");
?><img style="visibility:hidden;" src="th2.php?f=<? echo $img_name;?>&width=110&height=80&u=images_small" />

<div>
<table border="0" cellspacing="0" cellpadding="0">
<tr><td>Foto: </td><td><form method="post" enctype="multipart/form-data" onsubmit="" >
<input size="10" type=file name="img" accept="image/*" /></td>
</tr>
<tr><td><input type="submit" value="vloz" /></td>
</tr>
</form>
</table>
</div>

</body>
</html>


the script uses another script th2.php to change the size of the image (u can select the maximal width and height) and save it, even the full size image is saved in 'images_full' folder :

CODE
<?
header ("Content-type: image/jpeg");//vygeneruje thumbnail

if(!$_GET[width]||!$_GET[height]):
$new_width=133;//rozmery do ktorych sa ma obrazok zmestit
$new_height=100;
else:
$new_width=$_GET[width];
$new_height=$_GET[height];
endif;
$nasobic=$new_width/$new_height;

$filename="images_full/".$_GET[f];
$path=$_GET[u]."/".$_GET[f];
$type=substr($filename,strpos($filename,'.')+1,strlen($filename)-strpos($filename,'.'));

if ($type=="jpg"||$type=="JPG"){
$obrazok =imagecreatefromjpeg($filename);
}
elseif($type=="gif"||$type=="GIF"){
$obrazok =imagecreatefromgif($filename);
}
elseif($type=="png"||$type=="PNG"){
$obrazok =imagecreatefrompng($filename);
}

list($width,$height)=getimagesize($filename);

if($width>$height*$nasobic)://vypocet rozmerov
$new_height=round($height*$new_width/$width,0);
else:
$new_width=round($width*$new_height/$height,0);
endif;
$obr=imagecreatetruecolor ($new_width,$new_height);

imagecopyresampled($obr, $obrazok,0, 0, 0, 0, $new_width, $new_height, $width, $height);

imagejpeg($obr,$path,100);

?>


save this code to th2.php
