Preloading images + caching them?

Hi

I’m working on an image viewer which is now almost completed. I have some thumbnails that are loaded in the beginning, and the image itself is loaded upon selection of a thumbnail. Now, I would like to extend my viewer by preloading all the images in the beginning.

At the moment I load every image into one mc_holder MovieClip. But this poses the problem that I can’t preload all the images inside that movieclip (without showing them yet), because I animate this movieclip.

What I would like to know is if I load the images once behind the scences in another invisible movieclip, will this mean that all the images will be loaded from the temporary internet files map when I click on a thumbnail? Or will Flash reload the images from the server?

Thanks for reading and your time.
