One of the first things we learned was that a measurements can be accurate or precise.

The accuracy of a measurement system is the degree of closeness of measurements of a quantity to that quantity's actual (true) value.

The precision of a measurement system, also called reproducibility or repeatability, is the degree to which repeated measurements under unchanged conditions show the same results.

In this case, I guess, we have a similar type of distinction: the photos might not be of the actual provider, but the photos are of a provider with very similar physical characteristics to that provider (ie: perhaps a tall, thin build, brunette with a good butt). Hence, the two questions.
