Well There's your problem =] jkjk

Code? I think I know what's going on here, however a little more info would be great.

#include<allegro.h>

int main(int argc, char* argv[])
{
allegro_init();
install_keyboard();

set_color_depth(16);
set_gfx_mode(GFX_AUTODETECT,640,480,0,0);

BITMAP *pic = NULL;
pic = load_bitmap("picture.bmp",NULL);
blit(pic,screen,0,0,0,0,480,360);
readkey();

destroy_bitmap(pic);
return 0;
}
END_OF_MAIN();

And if anyone can guide how to attach graphics.h with dev cpp....it would be great :)
