I learned many things about copyright in the computer lesson. These are interesting for me because I didn't know before. Actually, I was surprised that we can only use 10% or 30 seconds of a song and 10% from a text and only 5 images from a single author. I think almost all teachers don't aware of these rules and they don't obey them. I don't know what about in my country, Turkey. I searched on the internet but I didn't find exact information but in my high school all my teachers were using any kind of pictures, texts or songs. I think if we don't get any profit from them, we can use. Unfortunately, there are rules and we should obey them ;)
