The internet can be a dangerous place and it’s important to know that you need to be carefully if you’re going to be sharing material that is created by somebody else. Images on Facebook and other social media networks are fine to share, but that doesn’t necessarily mean that you can use their image to promote your own or make money from it.
Photographers especially have to be very careful online and that’s why many of them will watermark their images, and make it clear that the copyright belongs to them. Written content can also cause problems and when you copy and paste content from somebody else’s website and try to pass it off as your own, you can find yourself in big trouble.
So the message here is always be cautious with the content you’re sharing or using online.
