Flickr is a website where everyone that has a camera of any kind can upload their images to show family, friends and/or future costumers. You can have it as your homepage or simply as a place to show the world your images. By getting constructive critism you can develope further and become a better photographer. But some photographers on Flickr choose to add their images onto the creative commons train.
Creative Commons is where the stock images are!
If you go to Flickr and put a word into the search field and press enter, the whole sites images associated with that word show up. The result that shows up is both stock and not stock. To reduce the result to just stock images you need to click on "Advanced search" and then scroll down on that page to Creative Commons. The rest should be obvious but if its not, click on the check box on "Only search within Creative Commons-licensed content" and check box click whatever suits your purpose.
How about the icons under each image?
