This image contains an artist signature that does not constitute a watermark, and should thus not be removed. In some cases it may be useful to provide a version of the file with such details cropped out or otherwise removed, but this should be uploaded as a separate file. For details see: what is not a watermark.
I received this photo after contacting the actress about adding an image to her Wikipedia article and she sent me a few images which she had approved and also signed a Public Domain release license for the images on the Commons site.
