I am asking out of curosity sake, what with the spat of copyright laws and what not that was done last year. How can one use for example an image in their work if they can't contact the poster of the image. What I am talking about is images from websites. Does one merely reference the website and when it was retrieved such as Figure : Example of a feral dog. Retrieved from website on November 22, 2012. http://icwdm.org/handbook/carnivor/FeralDog.asp Is that enough to cover the "copyright" factor nowadays?
