SFML sf::Image rotation

RotateImage.h

// Small code for rotating an image
#include <SFML\Graphics.hpp>

void rotateImage(sf::Image& image)
{
	sf::Vector2u size = image.getSize();
	sf::Image rotated_image;
	rotated_image.create(size.y, size.x);

	for(unsigned int col = 0; col < size.y; col++)
	{
		for(unsigned int row = 0; row < size.x; row++)
			rotated_image.setPixel(col, (size.x - 1) - row, image.getPixel(row, col));
	}

	image = rotated_image;
}

Removed all my specific code.
