For our first installment of #TwitterTuesday, we asked you to share your favorite photo from your first week on Flickr with us. For some of us this was surely a wonderful walk down memory lane. These are some of our favorites from your submissions.

Thanks to everyone who participated. We will be back with a new theme next Tuesday.

Check out all your submissions and follow us on Twitter to see the next challenge announced directly in your feed.
