We recently announced that we were beginning to roll the sidebar image uploader and author photo configuration options out of Beta.
We're happy to announce that the rollout is now complete and all users should have these options in their account. You can find both of these features by going to Design > Content.
As always, our helpful Knowledge Base has more information on both the sidebar image uploader and the author photo configuration options. You can also get personalized help from one of our Typepad experts by clicking the Help tab and creating a new ticket.
