You're free to feel how you feel just like she's free to show her beauty.

She's not responsible for how you feel any more than you are for her sharing the photo.

It's your world to live in. You can take it as it is or wish that it were another way. That, or you can try to take action to right what you believe is wrong, but that requires a lot of energy that can, and likely will, be wasted if the majority of people disagree with your stance.

The option is yours.
