Foros Club Delphi - Guardar Imagenes en MySQL

Si no me equivoco seria con esto(esta algo largo ):

la clase es esta:
<?

class clsImageManager{
var $db_abstraction;
var $added_image_id;
function clsImageManager($dblayer) {

$this->db_abstraction = $dblayer;
if (!$this->db_abstraction->table_exists("images")) {
$this->db_abstraction->create_table("images","id INT NOT NULL AUTO_INCREMENT, image_data LONGBLOB NOT NULL, image_width INT NOT NULL, image_height INT NOT NULL, image_type CHAR NOT NULL, image_size INT(7) NOT NULL , PRIMARY KEY (id)");
}

}
function addImage($img_holder) {
$theInfo=getImageSize($img_holder);
if (($theInfo[2]>=1) and ($theInfo[2]<=3)) {
$fields=array("image_data","image_width","image_height","image_type","image_size");
$values=array(base64_encode(fread(fopen($img_holder, "r"), filesize($img_holder))),$theInfo[0],$theInfo[1],$theInfo[2],filesize($img_holder));
$this->db_abstraction->insert("images",$fields,$values);
$this->added_image_id=$this->db_abstraction->insert_id();
} else {
$this->added_image_id=false;
}
}
function addDirectory($thePath) {
$directory=dir($thePath);
while ($entry=$directory->read()) {
$this->addImage($entry);
}
}
function removeImage($id) {
$this->db_abstraction->delete("images","id=$id");
}
function getImageSize($id) {
$this->db_abstraction->select("*","images","id=$id");
list($id,$image_data,$image_width,$image_height,$image_type,$image_size)=$this->db_abstraction->fetch_array();
return array($image_width,$image_height,$image_type,"width=\"$image_width\" height=\"$image_height\"");
}

function getScaledImageSize($id,$maxW,$maxH) {
$this->db_abstraction->select("*","images","id=$id");
list($id,$image_data,$image_width,$image_height,$image_type,$image_size)=$this->db_abstraction->fetch_array();
if ($image_width>$maxW) {
$ratio=$maxW/$image_width;
$image_width=$image_width*$ratio;
$image_height=$image_height*$ratio;
}
if ($image_height>$maxH) {
$ratio=$maxH/$image_height;
$image_width=$image_width*$ratio;
$image_height=$image_height*$ratio;
}
return array($image_width,$image_height,$image_type,"width=\"$image_width\" height=\"$image_height\"");
}

list($id,$image_data,$image_width,$image_height,$image_type,$image_size)=$this->db_abstraction->fetch_array();
switch ($image_type) {
case 1:
header("Content-type: image/gif");
print base64_decode($image_data);
break;
case 2:
header("Content-type: image/jpeg");
print base64_decode($image_data);
break;
case 3:
header("Content-type: image/png");
print base64_decode($image_data);
break;
}
}
}
?>
