Is it ok for her to do that?

I used to look ugly when i was in my early adolescent years, but i was naive so i didn't really think of it much. We took a lot of pictures with my siblings. But recently my sister posted few pictures of us and i look so bad n she even tagged me with a laugh. I know she is only having fun messing with me and embarrassing me but i really didn't like it. I look so different from back then and it is so embarrassing and i don't feel good people seeing me in that. If i say anything on there i will just embarrass myself more.
