The next several days we will be sharing cool tools and tricks you can use with Flickr. Flickr is an online photo management and sharing application. It's a great way to easily upload your photos and keep them organized, then use them on your blogs or web sites through cool widgets. Flickr photos can be uploaded through your desktop, your email, or even your camera phone. You can also geo-tag your photos, edit your photos right on the site, and even create buyable prints and photo books.
