You just need to declare them static like in java.  But it's a bit different
to handle.  an example for your bullet problem:

in your .h file
class Bullet
{
...
static BITMAP * graphic;
};

in a .cpp file:
BITMAP * Bullet::graphic = NULL;   // this must be global, outside any
functions.

then in a function, any function, you can load the graphic:
Bullet::graphic = load_bitmap(...);

and to use this, use it like any other member data for member functions.

I've only used static variables as public instance variables.  I think you
can handle private instance variables the same way, but don't quote me on
that.
