Why you need permission
If you’re using or changing materials protected by copyright, you need to get permission to do so. This is so that you avoid infringing legal rights, but also to ensure a creator gets paid for their work.
For example, you may be infringing copyright if you do any of the following without paying or having permission (the list is not exhaustive):
download films from the internet
make copies of DVDs
download images from the internet and use them on your website
perform live or playing recorded music in public
photocopy and distribute parts of a book, newspaper or magazine.
Ignoring copyright damages the creative industries
Every time somebody ignores copyright, the copyright holder is deprived of royalties (payment for use of their work). It goes without saying that if people don’t get paid for their work, the creative industries will struggle to exist.
