New profile picture?

I think you have to change your own unless you are a very big star. She might not bother - or maybe she will now she's been making her way into the public eye again. Some people prefer photos of themselves when they were acting compared to now. For example, Shirley Temple's photo is quite old (and used to be a child one).

She made some snarky remark about IMDB in her Matilda review with Lindsay Ellis (Nostalgia Chick). I don't think she is a big fan of the website and doesn't really care about the picture since she isn't acting seriously anymore. Anyway, I'm pretty sure actors or their publicists are the ones that get the pictures changed. There are tens of thousands of actors on IMDB. They don't have the staff to do this on their own.
