Is it infringement to draw pictures online according to copyrighted photos?

Is it infringement to draw pictures online according to copyrighted photos? China's Copyright Law points out that those who meet the following conditions and indicate the original source of the original author are not infringing: 1, copying for the purpose of learning, reference and appreciation, and the copied works shall not be sold for profit. It is not infringement, but at the same time, it should explain the original source, author and other real information of the original work. 2. Introduce and share other people's works, and quote other people's works in your own articles, videos and works. 3. Performing a work that has already been performed without obtaining economic benefits or paying remuneration to the performer. 4. Published articles are published for the second time by the media (except those who refuse to reprint). 5. Public speaking (except those who refuse to reprint through any media). 6. The scientific research department partially copies the collected works for the purpose of teaching or scientific research and cannot publish them. 7. Photos and paintings on display in public. As can be seen from the above provisions, whether there is infringement of intellectual property rights depends on the purpose of using the original works with copyright. It depends on whether this kind of behavior is profitable. There is a clear point above that even scientific research departments cannot publish for the purpose of academic research and teaching. Publishing involves profit. So if students want to copy other people's paintings or photographs, and truthfully indicate the original source of the original author's works, and do not sell copies. Does not constitute infringement. However, it should be noted that if you copy someone else's paintings, it is also an infringement to directly publish that you are the original author of the works, although it is not profitable to sell them. If you want to copy other people's works and show them in public, one is to explain the original work of the original author in detail. Second, you can get in touch with the original author and get his approval. Another of the above provisions is that paintings and photos in public can be copied. One kind of intellectual property rights is that after the death of the original author, the legal rights of the original work are transferred to his heirs. Fifty years later, the work became public copyright. Works with public copyright can be recreated and copied.
