The key goals of The Commons on Flickr are to firstly show you hidden treasures in the world's public photography archives, and secondly to show how your input and knowledge can help make these collections even richer.
Wylio is an image search engine designed to help bloggers and others quickly find, cite, and use Creative Commons licensed images. Wylio results only return images that are listed with a Creative Commons license. Wylio makes it easy to give proper attribution to the creator of the image by providing you with html code that includes attribution. All you have to do is copy the code and paste it into your blog post or webpage.
