It's possible that your friend is sending you pictures because she enjoys your attention and wants to keep in touch. If the pictures are casual or mundane, she may just want to share her life with you as a friend. However, if the frequency of the pictures is high, it could also mean that she wants you to know more about her and is inviting you into her world. Alternatively, if the pictures are similar to you, she may be seeking validation or comparing herself to you. It's important to communicate with your friend and express your thoughts and feelings about the situation to ensure a healthy and understanding friendship.
