Could somebody please tell me why the photo of Diana has a caption Helper?

While Diana was a Princess she did a great deal to help those in poor situations, she travelled to 3rd world countries a lot, and did a lot of work especially in the last year of her life working to ban landmines. She tried to help raise awareness for diseases such as AIDS and Leprosy which had often been overlooked by the Royal Family previously. She did a great deal to raise awareness of others situations and raised a lot of money to help people which is why she has been put in the helper category.
