1. Set up three layers in a new movie. Name the first one "loader", the second "actions", and the third "picture".

2. Create two text boxes. Go into the Type pallet, and place it as Dynamic Text with Variable names "totalbytes" and no options checked. Give the other variable the name "loaded bytes".

3. Place this text field in the loader layer.

4. In the picture layer, import a large picture of your choice. Make it 5 frames long, and make the last frame a key frame. Then, delelt the first four frames, leaving just the fifth. Name the fifth frame "end frame". Insert the stop(); action into this layer.

5. Now go to the actions layer, and create two key frames.

6. In the first key frame, insert the action:

loadedbytes = getBytesLoaded()/1000;  

totalbytes = getBytesTotal()/1000;  

if (loadedbytes == totalbytes)  

{  

gotoAndPlay ("endframe");  

}

7. In the second key frame, insert the action:

gotoAndPlay (1); 

8. Press Ctrl+Enter twice on your keyboard. It’s done! The preloader is complete.
