From my research, I've learned that once you upload a picture on social media, you technically still hold the copyright, but the reality gets a bit murky. When you accept the terms and conditions of platforms like Instagram or Facebook, you're giving them a license to use your content pretty much however they want. It's important to remember that even if you delete the picture later, they can still use it. So, while you may own your photo, its use is largely out of your control once it's online. It's a crucial reminder to think carefully before sharing any image on the web.
