The right way to access to file element by POST method is not $img = $_POST['photo']. You should use $_FILE var, for example $img = $_FILE['photo']['name'] to get the name of file.
There are some different info you can get from $_FILE var:
$_FILES['photo']['name']
The original name of the file on the client machine.
$_FILES['photo']['type']
The mime type of the file, if the browser provided this information. An example would be "image/gif". This mime type is however not checked on the PHP side and therefore don't take its value for granted.
$_FILES['photo']['size']
The size, in bytes, of the uploaded file.
$_FILES['photo']['tmp_name']
The temporary filename of the file in which the uploaded file was stored on the server.
$_FILES['photo']['error']
The error code associated with this file upload.
Look here: http://php.net/manual/en/features.file-upload.post-method.php
Pay attention: If you need to store the image in DB you need to convert file in binary data and store in DB as BLOB type.
Look here: http://dev.mysql.com/doc/refman/5.0/en/blob.html
As alternative, a good way is to store the file in a folder on your host and save the path in a DB.
