[Image-SIG] tiff with 16bit/channel

[Fabio Marcone]

Hi!
this is my first post here. I'm using PIL to create a thumbnail (jpeg) 
for an image tiff with 16 bits per channel but I got an "illegal 
conversion" error.

Is there a way to solve it?

if not, is there a way to modify pil to transform from 16 to bit image 
before load it in memory?
someone can suggests me where I have to apply changes in source code?

thanks in advance,
Fabio Marcone
