Hi everyone, There was a question about citing photos in Flickr. I cover that in the #4 post but I have pulled it our here in this tip for easy reading:
A quick word about photo posting etiquette…when posting identifiable photos of other people (especially minors) is it advisable to get the person's permission before posting their photo in a publicly accessible place like Flickr. Never upload pictures that weren't taken by you (unless you have the photographer's consent) and always give credit when you include photos taken by someone else in your blog. Also, you might want to check out the Creative Commons licensing explanations in Flickr - you can search by license type.
Basically, if the photo is labeled "Some rights reserved" under Additional Information it's ok to post it on your blog if you credit the photographer.
