You can choose to block external images in emails. Turn this on by going to Settings and tapping on the account where you'd like it enabled.
All of our weekly updates also include performance improvements and bug fixes to make Outlook better for you
Incidentally, Gmail started showing images by default years ago, but circumvents potential privacy concerns by using proxy servers.
