Obviously a picture server doesn't serve pages.

How could a server waste resources by doing the job it is dedicated for?
Does a database server waste resource by answering SQL requests? If
there's a server (even a virtual one) dedicated to serve pictures in
various formats, how could it waste resources by doing exactly that?

So you know beforehand which resources will actually be requested by
your visitors? Do you also know the lottery numbers for next week?

With a million images there's a good chance that a lot of them will
hardly be requested, if ever. I consider it a waste of server and
network resources to pre-calculate and upload all of them at once.
If there's a picture server - let it do the work as necessary.

Doesn't seem to happen here. Obviously the EC2 cloud does exactly what
it is intended to do and paid for.

In a cloud environment CPU power is the least problem.

No paragraph of you without insults, directly or subtly. You can't live
without that, right?

You can't plan your visitors.
