You Can Pin Images to Pinterest from Bing Image Search
Here's one for you dedicated Pinterest pinners: Pinning Feature Now in Bing Image Search at Geek Sugar. If you've been searching for images using Google, you might want to consider Bing instead.
The beautiful part, as Geek Sugar writer Kelly Schwarze explains, is that Bing credits the original source of the image when you pin it. That helps relieve any copyright worries you might have about pinning images to your Pinterest boards.
