Dragging the stage newbie question

Question

I'm using Flash CS3 and wish to create a movie where the stage is a certain size but the actual content of the movie extends further than the stage. The user will be able to drag the stage from left to right to show hidden parts of the movie. Similar to the idea of a horizontal scrolling image gallery but without the scrollbar (see attached for example image). Does anyone know how this is done or where I can find a tutorial explaining how to do it?
Cheers

I have done this type of interaction (AS2), not left to right, but up and down, so you will have to make some adjustments.
I placed the large image on the stage converted it to a movieclip and gave it an instance name of mc_portletlist.
I then created a mask for the area I wanted the image to be visible.
This is optional, but I created a popup that tells the user what to do (btn_popup).
I then placed the code below on the actions layer.
The numbers limit the movement of the image, so if you want the user to be able to move the image around without limits, just remove them.
    mc_portletlist.onPress = function()
btn_popup._visible = false;
    btn_popup.onPress = function()
btn_popup._visible = false;
mc_portletlist.onMouseDown = function() {
mc_portletlist.startDrag(false,462,35,462,737);
mc_portletlist.onMouseUp = function() {
mc_portletlist.stopDrag(false);
