I'm doing an android app that sends me a form together with an image to the server but the images come out horizontal. That is, I'm going to the server and I see that the image is saved but horizontally

This is the android code

I think the problem is with my php (web service)

This is the php code

<?php

require("conexion.php");

$image =$_REQUEST['image'];
$user = $_REQUEST['user'];
$password = $_REQUEST['password'];
$nick = $_REQUEST['nick'];
$email = $_REQUEST['email'];
$edad = $_REQUEST['edad'];
$distrito =$_REQUEST['distrito'];
$descripcion =$_REQUEST['descripcion'];
