It's a start.  Don't feel bad.  I had problems with this too.  Take a
look at my post above, or you can just look at this bit of code
instead... (It might help to view this with a fixed-with font.)

#include <stdio.h>
#include "allegro.h"

BITMAP *bitmap_name;
PALETTE palette_name;

main()
{
	allegro_init();
	set_gfx_mode(GFX_AUTODETECT, width, height, 0, 0);

        /* Load our bitmap into memory. */
	bitmap_name = load_bitmap("filename.xxx", palette_name);

	set_palette(palette_name);

	/* Display the image on the screen. */
	blit(bitmap_name, screen, 0, 0, (SCREEN_W-bitmap_name->w,)/2,
		(SCREEN_H-bitmap_name->h,)/2, bitmap_name->w,
		bitmap_name->h);

	/* Wait for a keypress */
	readkey();
	destroy_bitmap(bitmap_name);
	return 0;
}

If any of this seems wrong to someone out there, let me know. :)  This
is how I did it by reading through the allegro docs and examples.
