I thought your page on "amazon-s3--how-to-use-Amazon-s3-as-an-image-hosting-service" was excellent.
I was somewhat familiar with the AWS services before this, but your help page on this one use case prompted me to sign up.
My image load is about 10x faster due to AWS vs cheap hosting.
Now, to complete the optimization.
It would be good to help and enable the user to set a far future "Expires" header on all of the files in the bucket to optimize browser performance further, and reduce AWS bandwidth charges.
I read somewhere that the default Expires header is set to the future + 15 minutes.
