Flickr is the name of an online application to which the Flickr Widget provides access. Through the Flickr Widget, Flickr enables you to manage and share digital photos—in fact, any image saved in the JPEG format. You can use Flickr for uploading images taken with your device's camera and for titling, describing, tagging, and setting security on the image during the upload process. You can share photos with the entire community of Flickr users or securely and privately share them with the Flickr users who are your friends and family. In return, your contacts—friends or family—can share their photos with you as well as leave comments about your photos. You can use searching to look for comments, tags, titles, and descriptions as well as a particular photostream belonging to a flickr user. Photo sets as well as your contacts' photos that you mark as favorites appear as another photo source.
To share photos using Flickr, sign in to your Yahoo! account (or create one) and create a Flickr account if you don't already have one at http://www.flickr.com. Because you have a Yahoo! account, you can easily set up a Flickr account that you need to have to use it. Note that although Flickr screen names and Yahoo! account names can be different, both names are tied to the same account.
