My girlfriend's nudes were leaked on the internet.

I was looking her face up as well as mine (bc I'm paranoid), and suddenly came across a censored pic from my search. It was her kinda posing with her feet up (seemingly nude) and I saw her face. My stomach instantly dropped. On this site you have to pay to uncensor it to see the full results and I did. It was even in her current room. I don't know what to do, I don't know if I should tell her, she already has a lot of stress in her life and I don't want to add any more. But this has been eating at me for days, and I just needed to tell someone.

What should I do? If I tell her I don't know what'll happen, but what'll happen if I don't tell her?

edit: i decided to tell her about it, so i will soon. i feel kinda stupid for even asking the initial question but yes she deserves to know if it wasn't her that uploaded it herself. also, she is not a SW, for all the comments saying that.

edit2: yes it's entirely possible she posted them herself but it seems unlikely from what ik about her. but, yes, a possibility for sure. ig i'll see from her reaction?
