Need some images for your new site or blog and don’t know where to download them? Don’t want to pay a hefty fee to download from one of hundreds of stock photography websites (especially if you have no revenue)? Look no further. Yotophoto allows you to search through hundreds of copyleft photos from such sites as Flickr and Wikimedia Commons.
Yotophoto allows you to search photos by category but by color too. And the search engine takes hexadecimal values.
Better yet, there’s even a Firefox Plugin for Yotophoto already available, so you don’t have to go to the site every time you want to search.
