I respectfully disagree with hexeliebe on this.
"You paid the photographer right? He was your agent in this deal? Therefore it is a work for hire and any copyright of the Photo belongs to you."
This is not the case. A "work for hire" exists in two specific cases: first, where the agent was an employee (as defined by applicable state rules) of the person, and second, when the work is part of a collaboration or other enumerated type of joint work as defined in 17 U.S.C. 100 or 101, I can't remember exactly which. Even work done by a contractor working for a company does not produce a "work for hire" if the contractor not considered as an "employee" by the state.
"He may have copyright on the process, the pose or the subject matter composition but you own the photos and can do as you wish with them as long as you do not attempt to protray them as your own product.
In other words, you can copy them, send them to modelling agencies, throw darts at them or post them on the web."
Its true that she owns the copies of the photos that the photgrapher sold her, but without a contractual agreement to the contrary, she does not own the copyrights, and therefore does not have the right to reproduce the pictures.
Unfortunately, unless you contractually agree to purchase the rights to the photos along with the photos, the photographer will still hold the copyright to the photo -- even if the photo is of you.
Your best bet is still to try and find out the whereabouts of the photographer and get his or her permission. Failing that, you should just go down and see about getting a copy made -- if all you want is a personal copy, you could always argue that making a single copy for your personal use is a "fair use" under copyright law. Besides, if the picture is of you, I doubt the photo people are going to ask you for a release -- usually they ask for a release when you want to make a copy of a picture of someone famous or the like. If you want to make a bunch of copies and distribute them, you are much better off seeking permission first...
