Form upload image to simple modify

i have the upload image it works fine uploading the image sends the image path to databse and copy the image to the images folder. but now i trying to just modify the problem is the image path goes to the database but now the image is no longer copied, or replaced with into the images folder do i need to chenge the copy image on the script with something else

here the upload image code

<?php
$con = mysql_connect(“localhost”,“root”,“”);
if (!$con)
{
die('Could not connect: ’ . mysql_error());
}

mysql_select_db(“admin”, $con);
?>

<?php
