I have a fan page full of original content (my own photography). I'd like to include royalty free content from other photographers. I notice that I have to include an attribution: in other words, I have to link to the original source. I know how I'd go about doing this on a website, but how do you suggest I do so on a FB fan page? I don't see anyone else doing it. Is it required under these types of licenses? Apologies if this is a stupid question. I'm no FB guru. I run a photography themed page on the weekends.
