Loading too much images and slow loading

[raphque]

For a project, I need to preload multiple depts of a map, to cache the images and do a smooth zoom. Eg. z=13 to z=19

The problem is, loading all those layers is very, very slow when it's the first time. I noticed that the first layer loads 71 images, whatever layer I start with. All the next layers that are loaded, load 23 images. It doesn't matter if I load from 13 to 19, or from 19 to 13. It's always the first layer being loaded that is the most heavy.

When I take into account the size of my movie and the fact that the images are 256x256 pixels large, I would need only 8 images per layer.
7 layers would mean 56 images, now I'm loading 209 images...

Is there a reason for this? Can I do something about it?
I don't need to pan, zoom or re-center after the final animation, so all the extra overhead is wasted.
Anyone has ideas or tips to improve this?

We preload additional column and row on each layer for pannig. Also first time it loads 4 layers: 2 layers on init and 2 layers when you zoom in. We will think of some methods or properties for you to change it, bu I can't promise it would be fast.
