[flexcoders] FLEX Images sandbox error

[noam.malter]

I am trying to write a simple application that retrieves my pictures 
from my Facebook account and then displays the images and run some 
effects on it, e.g. fade, move, iris etc. Everything seems to work 
except for the iris effect. I have done some research and found that 
when I import pictures from another domain and want to work on their 
bitmap data I need to set the checkPolicyFile property on the loader. 
I did that and then I get an error 'No policy files granted access'. 
The code is provided below. Any help is appreciated.

Thanks,
Noam
