And if i load icns, work on it, then i cannot save..... Can someone tell me something about it? Someone have tried? That is correct, this is read-only support. You may not save icns files with the code in PIL. But starting by reading a icns, i can save a png or jpg?

Yes, of course. Image.open('myapp.icns').save('myapp.png') will probably Just Work.

You could of course do it the native way, using Mac APIs, or just by dragging images into Icon Composer. There is a fast way to produce icns starting from a 128x128 image (format Png, jpg doesn't matter)? What Mac Api i must use? I've search documentation, but found about nothing (maybe I'm not able to search), i want write a python program to convert images in icns in a background fast way, i can't drop 1000 image con icon composer =)

The easiest way would probably be to use IconFamily from PyObjC <http://homepage.mac.com/troy_stephens/software/objects/IconFamily/>.
Carbon is always a pain in the ass, but the Icon Services functions may be wrapped (not sure?). NSImage will load pngs and jpegs quickly and easily.
