Hey Rich,
Usually when you set your model up on the judging table and give the outline judge your 3 views he or she will ask you if there are any differences between your model and your outline you presented to them. At that time is when you point out the photo's and let the judge know about the differences, As long as your model is built as the version in the photo's and not the 3-view you are good to go.

You will find that if you get 4 or 5 different 3-views and compare them you will get 4 or 5 different measurments from each one, it can be really frustrating trying to build a model from 3-views!
