Hi Taha,
Welcome to the real world. ;-)
ever Want to use my own photos anywhere.
They are _her_ photos. She pressed the button, she has the negatives, digitals whatever, but you've still got your face. Next time, sort out the paperwork first.
In the meanyime, let her do the donkey work of getting your face plastered everywhere, doing the advertising for you. If its the competition winning entry, well it is just your face, isn't it, no interesting background. I guess it was she who won the competition, not you, she entered her photo. You needn't work with her again, unless you've signed some wrong paperwork. Maybe you need to get an agent or someone. It is very, very difficult to mix business and friends, it is very difficult to make business partnerships work.
wrt to the tv, if you just wanted the publicity, great, you're getting a few more years for free.
When this stuff happens, you feel pissed off, let down, etc. But, you will move on. It is all part of the rich fabric of life. I learnt this sometime ago, I have my own way of working through similar problems. At the end of the day, it's only money, and that is cheap.
Best wishes,
Ray
