Hello,

Follow these steps

1) In the timeline rename Layer 1 to Actions. Click on the first frame and hit
F9 on your keyboard or go to Windows>Actions.  Copy and paste the code above
into the Actions Panel.

2) Create a new layer and name it Background.  Drag the layer under the
Actions layer.  Go to Insert>New Symbol.  In the Create New Symbol box that
appears, choose Movieclip for Type and give it a Name (bkg_mc will suffice for
now).  Click OK to close. You will now be inside the bkg_mc timeline.  Click on
either the Scene 1 link or the back arrow to go back to the Main stage.

3) If it hasn't been done yet, make sure your stage size is the same as the
background JPG images you're going to use.   Go into the Library and drag the
bkg_mc onto the stage.  In the Properties panel, give your movieclip an
Instance name of mtClip.  While still in the Properties panel set the X and Y
to 0.

So what you've done is created an empty Movieclip symbol and placed it on the
stage.  This Movieclip symbol has been given the instance name of mtClip (which
is referred to in the script) and placed in the top left corner of the Main
stage.  This is the clip thats going to load your background JPGs.

Save your movie in the same folder as the background JPG's your going to use
and then go to Control>Test Movie to preview your movie.  If all went well you
should see a different background everytime you preview your movie.

Hope that helps
