CCFinder is shorthand for Creative Commons Finder. CCFinder helps you to easily find pictures which were publicized under the Creative Commons License. CCFinder enables you to search based on specific usage criteria and shows you what you may do with each picture. This means that you can re-publicize most of the pictures found, for example on your website.
Find and download pictures with a creative commons license from Flickr based on your search terms. Define how you want to use the picture (commercially, if you want to change it, etc.) and only find pictures with appropriate licenses.
CCFinder allows you to put a color filter on the picture to change its looks. It shows you which license a picture is published with, how you may use it and what you need to keep in mind when doing so. You can download pictures, go to the source in the internet or directly use it as your desktop wallpaper.
