After reading this article, I’ve learned that every time you use other work, you have to be careful, and you have to think about copyright. In Susan’s perspective, she thinks Joy violated the person in the photo, which also let her be to claim the image of Pablo Arauz. Her intention was to praise the people of the time and the movement, but Joy changed the meaning of the picture. At the same time, Joy’s change caused a series of problems. This image was used over and over again for other activities that neither of them had anticipated. From this, we can see that every time this image is used, there are copyright issues involved. At the same time, every user seems to ignore this problem. If Joy at the time was able to think more about the copyright issue and whether he had the right to use this character to create a new paint., if other online spammers had been able to consider Joy’s copyright, the image would not have been so widely used without permission. From here we can see, in the age of the Internet, copyright issues are worth thinking about. Each time online work reprints and reuses, people should confirm the right of this work. Every web user should also consider whether a careless act of his own may push the original author into great trouble. At the same time, the government should also fine-tune the rules governing Internet copyright in order to better manage this issue.
