I think you meant to say:
"That is the best pic of hers I have ever seen."

No, Erasmus. "The best pic of hers" means that she owns the picture. He is correct to say that it is a pic[ture] of her.
If I had meant to say that I would have put an apostrophe between the r and the s in her's. I don't care if she owns the picture. It's of her, and that is what counts. It's the best picture of her I have seen.
