flash actionscript: Hi

I am completely new to Flash and all help is greatly apreciated!!

I have a rectangle symbol (holder1) which I have made stretch and shrink as
though it is spining around an axis running from the top to bottom of the
screen. (IE in and out of the page)

I want to load up an image into the holder and then, when the holder has spun
180 I want a second image to replace it.

I have got the first image to load, using code from one of the tutorials but I
dont know how to make it change.

The change needs to be triggered every 240 frames.

Ideally I want it to select a random image from a selection and to act as a
button that does to a different action depending on what image is displayed
when it is clicked.

My code is as follows:
var image0uri:String = "images/toro0.gif";
var image1uri:String = "images/toro1.gif";
var image2....etc



var currImage:Number = 0;
var totalImages:Number = 7;


loadMovie(this["image"+(currImage)+"uri"],"holder1")

Not sure the specific questions but if you have potential delay with loading
external swf movies which will prevent guarantee of continuous play. You may
want at least two holders so the next image can be loaded and ready to go
before it is needed on a frame's notice. If you always have 7 images, then I
would go with 7 holders.

With two you load the next image alternately into the non active holder so
it will be ready when needed. You can use the _visible property to hide and
show the holders as you hit your swap point. You would need to set the
rotation of the next holder just before you make it visible.

Thanks for your reply. I didn't realise what a rabbit hole this is!

My question is simply how does one make an image load on to a moviesymbol in
flash, and then 240 frames later to load a second image onto that same symbol,
and so on.

Since the original post I have made two symbols. "holder1" and "holder1b"
They both start behind a black rectangle. First 'holder1' stretches out
sideways and comes back in. then hoder1b does the same action. Through tween
and ease It makes a fairly realistic effect of spinning.

My actionscript is, as recommended in the tutorial, in frame 1 of its own
layer in scene 1.
I am using loadMovie(this["image0uri"],"spinning_spinner_wheel1.holder1")
to load the image
the trouble is if I load a picture onto it I can only do it if the symbol
exists in frame 1. As holder1b doesnt appear until frame 240 it doesnt load its
image. If I make it exist in frame 1 then as it is above holder1's layer, it
appears throughout holder1's 'turn' .

How would you go about achievng my objective? THANKS A LOT

PS. My images are small (75 x 75 px (1.8 Kb)) so I dont think I need to worry
about loading the next image.
