If you have allegro, you can use the following lines of code as an
example:

#include <allegro.h>

#define XRES 640 //The horizontal screen resolution, can be changed.
#define YRES 480 //The vertical screen resolution, can be changed.

BITMAP *test;
PALETTE p;

int main()
{
 allegro_init();//Activates Allegro
 install_keyboard();

 set_gfx_mode(GFX_AUTODETECT,XRES,YRES,0,0);//Defines the graphic screen

 test=load_bitmap("picture.bmp", p);//Loads test BMP into memory.
 set_palette(p);//Sets up a palette with color scheme from BMP.
 blit(test,screen,0,0,0,0,test->w,test->h);//Showes BMP on the screen.

 readkey();//Waits for a key to be pressed.
 allegro_exit();//Exits Allegro.
 destroy_bitmap(test);//removes BMP from memory.
 return 0;
}

Hope this can show you the way ;)
