Sure,

Here's a little something that might help you. A little program.

void main(void)
{
    BITMAP *the_image;   // This is probably the most important thing 
			 // The image is stored here when you've loaded it

    int x,y;		 // Just some coordinates for locating the picture
    x=160;
    y=100;
   
    allegro_init(); 		// Let's use Allegro
    install_keyboard();	// To use the Allegro Keyboard functions we have to
			// call this.

    set_gfx_mode(GFX_VGA,320,200,0,0); // Set the grafics mode to 
					 // VGA (13h) more information in 
					 // The documentation

    the_image=load_pcx("filename.pcx",palette); // This is the function you
			// have to use for loading .pcx-files, I havent used
			// the others, so I don't know about them, but 
			// surely you can find them in the documentation

    create_bitmap(10,10); // Before you can use the bitmap, you have to
create
			// it by telling it's size.

    set_pallete(palette);   // Sets the loaded palette
 
    while(!key[KEY_ESC]){  		// While no-one has hit ESC
        blit(the_image,screen,0,0,x,y,10,10); 
			// Blits the image on the screen from (0,0) to
			// (x,y) - the size of the image is 10,10

        // Keyboard
        if(key[KEY_LEFT]) x--; // if you press left..
        if(key[KEY_RIGHT]) x++;
        if(key[KEY_UP]) y--;
        if(key[KEY_DOWN]) y++;
 		// This is easy.. just: key[KEY_name_of_the_key]
		// ie. key[KEY_ALT] or key[KEY_A]

   }
   
   allegro_exit(); // Makes everything as it was before
}

There might be some faults in this program and it's not very good.
It doesn't use double buffering (wich you should use..) or any other
nice stuff. But it does what it's supposed to do (I hope so, I haven't 
tested it, I just wrote it here for you). Hope you find something
in it. Good luck.
