SDL 2.0 Issue - Trying to load image, but only get a white box - image

Question

Okay, so I am trying to load a window and display a couple of images on it using a function. The window loads and my errors don't display for a failure to load the image, however the window just stays white. Any ideas why that might be? This is my code below.
#include "stdafx.h"
#include "SDL.h"
#include <iostream>
#include <string>
using namespace std;
const int Window_Width = 640;
const int Window_Height = 480;
SDL_Window *window = NULL;
SDL_Renderer *render = NULL;
SDL_Texture* loadImage(string imagename) //function that loads the image, useful for handling multiple image imports
{
SDL_Surface* loadedImage = NULL;
SDL_Texture* texture = NULL;
loadedImage = SDL_LoadBMP(imagename.c_str()); //loads the image with the passed file name
if (loadedImage == NULL) //checks for any errors loading the image
{
cout<<"The image failed to load.."<<endl;
}
texture = SDL_CreateTextureFromSurface(render, loadedImage);
SDL_FreeSurface(loadedImage);
return texture;
}
int main(int argc, char** argv)
{
if (SDL_Init(SDL_INIT_EVERYTHING) == -1)
{
cout << SDL_GetError() << endl;
return 1;
}
window = SDL_CreateWindow("Frogger", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, Window_Width, Window_Height, SDL_WINDOW_SHOWN);
//creates a window in the centre of the screen, it uses const int's to define the size of the window
if (window == NULL)
{
cout << SDL_GetError()<<endl;
return 1;
}
render = SDL_CreateRenderer(window, -1, SDL_RENDERER_ACCELERATED | SDL_RENDERER_PRESENTVSYNC);
//this renders the window
if (render == NULL)
{
cout << SDL_GetError()<<endl;
return 1;
}
//loading the images using the function
SDL_Texture* background = NULL;
SDL_Texture* frog = NULL;
background = loadImage("background.bmp");
frog = loadImage("frogger.bmp");
SDL_Delay(2000);
SDL_RenderClear(render);
SDL_RenderPresent(render);
SDL_UpdateWindowSurface(window);
//freeing the memory back up
SDL_DestroyRenderer(render);
SDL_DestroyWindow(window);
SDL_DestroyTexture(background);
SDL_DestroyTexture(frog);
SDL_Quit();
return 0;
}

You aren't rendering anything, you just load some textures and end the program.
