Flickr has a fantastic, easy feature to post your Flickr picture in your WordPress Blog. First, add your blog to Flickr by logging into Flickr, going to your account and selecting add a blog.
Now you only need to visit your photo while logged in and click “blog this”. You’ll be asked to fill out the description and info *within Flickr*. After completing that and selecting “Post Entry”, your picture and the information you added in Flickr automatically become your WordPress blog post. Neat!
