A picture can provide enough spark to change the dynamics of a whole paragraph, and it can be a catalyst in a blog that makes people want to read more. Most people aren't photographers and if they are, they aren't able to access many sources for a picture related to their article. There are many photo hosting websites on the internet, like Flickr, with a bounty of pictures that could be used for almost any occasion. But, to what extent can we use the pictures? Do we have to give them credit? Link back to their Flickr page? Or do the pictures become free to all since they are published on the internet?
