There are two ways to add photos to a blog post: uploading from Flickr using a photo's URL link, or uploading directly from your computer's hard drive. To upload from Flickr, you first locate the photo on Flickr and copy its URL. You then paste the URL into the blog post where you want the photo to appear. To upload from your hard drive, you click the "Choose Files" or "Browse Uploader" button to select the photo file from your computer and upload it into the blog post.
