I like Flickr, not just for a place to upload my photographs, but also as a place to find photographs. Regular readers of the blog will know that I use images often to illustrate my writing. Some of these are mine, but many are creative commons licensed images from Flickr.
It’s very easy to search for creative commons licensed images on Flickr, but getting to the advanced search is not the easiest route (or if it is I haven’t found it). So I usually add the direct URL as a bookmark or a favourite.
Another way to search for creative commons licensed images is to use the search box on the creative commons website.
