Good answer - and as I would not want to pay for (what must be pretty large) bandwith - so I can certainly live with that.

Now, just a theoretical enquiry; I know it is not going to happen. If you were to allow links to other photos on the web via the img and /img HTML instructions, would it actually increase your bandwidth substantially? Just asking out of interest.
