Gradual swap one bitmap for another?

Question

I am trying to swap one bitmap for another over a few
seconds. I can't get it to work. Is this a motion tween or shape
tween or what?

It sounds like you're using two words to describe the same
technique --
but I'm not sure. To me, a morph is when one raster image
slowly
metamorphoses into another. If photo A is a dog, and photo B
is a cat, the
area that represents the dog's nose literally changes shape
to become the
shape of a cat's nose The dog's ears may grow, warp, or
otherwise distort
to become the shape of the cat's ears, and so on. Fading
generally
describes a dissolve: nothing in either image changes shape;
it's just that
one image slowly becomes more transparent, revealing the
image beneath it.

If you're after morphing, as described above, you'll find
that Flash
doesn't support it. If you're after a dissolve, you can
achieve the effect
easily by putting two photos into their own symbols, as
you've done, and
each symbol in its own layer, one atop the other. Put two
keyframes in the
upper symbol. At the first keyframe, make sure the symbol's
Alpha property
is 100. At the second keyframe, make sure the symbol's Alpha
property is 0.
Motion tween the span of frames between those two keyframes,
and you'll have
your dissolve, aka fade.
