Blogger has extended the comments feature it annoucned last year, which lets users embed comments and the commenting form below blog posts. The feature has been extended to display profile images next to comments that blog visitors write.

"Though profile images have been available with the other commenting options, we are happy to bring them to embedded comments as part of the Blogger Birthday feature series," says Lu Chen of the Google-owned Blogger.

The series Chen refers to has so far included things like:

- a partnership with Blog2Print tha allows users to turn their blogs into books

- a partnership with Widgetbox , which allows users to turn blogs into widgets

- jump breaks, which let bloggers show a snippet of a post on the blog's index page with a "read more" link

- the SocialVibe gadget, which lets bloggers earn donations for charitable causes

- the Blogger NavBar, which lets blog readers click to share blog posts/blog hompages

- the label cloud and selected labels - extensions of the labels gadget

- the send to feature, which lets users send posts to Blogger

- support for the PubSubHubbub protocol

As part ot today's announcement, Blogger has also made it easier to upload profile pictures when you leave a comment. From the comment preview, users can just click "add a photo" and upload one. The next time they comment on any Blogger blog, their photo will appear.
