What is Public Domain? Can I use a public domain material on my site?
I wanted to know that what is a Public Domain material? I was writing a article to my blog then I came across wikipedia while searching for relevant images for my post. Then I found license terms at the end of image that it has been made public domain by its Author. So can I use that image? Should I have to link them back? or Just attribution with Author name would be enough?
