How are people getting AI-generated images of themselves?

Have you heard about the growing trend of AI-generated images of individuals? I'm curious, how exactly are people getting these images made of themselves? Are there specific apps or websites that offer this service? Are the results realistic, or do they have a distinct AI-generated look? I'm also wondering if there are any privacy concerns surrounding the use of these AI-generated images, and how people can ensure their personal information remains safe. Can you shed some light on this fascinating phenomenon?
