*First frame preloading*


Is it possible that contents (huge) in the first frame will detect preloaders scripts?when the contents are being exported to the first frame? I know one solution that the instance of the image or a movie clip can be used. But when I am using dynamic content I cant use instances anyway.

So my question is, While using dyanamic content which is being linkaged to the first frame IS IT POSSIBLE FOR PRELOADERS TO DETECT?
