I'm new and I have some questions, if I copy an image from the internet, for example a movie cover, and I edit and customize it in 'canva', adding more things to the image. Would I have to put the source? Or the image would not break the rules if I placed it without a source... because the image would be taken from the internet but edited by me... O_O could you clarify my doubt so as not to make mistakes in the future?
