I am Working on a cs5 as3 project and in that project i have writen all code in the frame1 of main timeline (there is no package/class in the code)
The code in the main timeline is very complex in which i am loading external images and xml’s and many more things .
i have not written any code in the action layer.
Now i want to add Preloader .
how can i add Preloader in this situation ?
here is a snapshot of the timeline :

Move everything to the second frame, and add your preloader code/content on the first frame
