Answer 1

Here is a simple example of how to achieve that:
if(is_uploaded_file($_FILES['image']['tmp_name'])){
$folder = "upload/";
$file = basename( $_FILES['image']['name']);
$full_path = $folder.$file;
if(move_uploaded_file($_FILES['image']['tmp_name'], $full_path)) {
echo "succesful upload, we have an image!";
$firstname = trim($_POST['fn']);
$lastname = trim($_POST['ln']);
$username = trim($_POST['un']);
$password = trim($_POST['pw']);
$confirmpassword= trim($_POST['cp']);
$stmt = $dbh->prepare("INSERT INTO registration (fname,lname,username,password, img_url) VALUES (?,?,?,?,?)");
$stmt->bindValue(1,$firstname,PDO::PARAM_STR);
$stmt->bindValue(2,$lastname,PDO::PARAM_STR);
$stmt->bindValue(3,$username,PDO::PARAM_STR);
$stmt->bindValue(4,$password,PDO::PARAM_STR);
$stmt->bindValue(5,$full_path,PDO::PARAM_STR);
if($stmt->execute()){
echo "YOUR REGISTRATION IS COMPLETED...";
}else{
echo 'YOUR REGISTRATION COULD NOT BE COMPLETED...';
}
} else {
echo "upload received! but process failed";
}
}else{
echo "upload failure ! Nothing was uploaded";
}
In the query I have included a field called img_url.
The PDO insert query is executed once the image is uploaded successfully.

You could just use a simple PHP upload() function. Here's an example http://www.w3schools.com/php/php_file_upload.asp
