I see this question asked a lot by both seasoned veterans & newcomers in Flickr so I’ll try to answer this as short as possible. The good news … it’s all FREE.

1. You need to use Mozilla “Firefox” as your browser. If you are not currently using it, you can download it here for FREE!
2. Install it of course!
3. Once you are running Firefox as your browser, you then need to install the Greasemonkey script available here for FREE too!
4. Restart your Firefox browser by closing and opening again.
5. Install the Buddy Icon Reply script available here.
6. Open your Flickr account, go to your photo post, and see the comments made by your contacts.
   You’ll now see it has a new feature added added to each comment after word “contacts said:”

Simply click on “name reply” if you want to answer the comment with your contact’s name, or click “icon reply” if you want to respond with your contact’s icon.

Easy huh!
