So we're literally resorting to stealing artwork now are we?
Was hoping my first post back here would be positive but you do this all the time. She told you you couldn't use that artwork, I'd suggest you use your own work, or something the person who designed it said you could use.
That being said, I don't think using a picture as an avatar would be considered stealing. Especially if that picture is just an edit of a photograph of an actress. That's hardly an "artwork" belonging to the person who edited it.
