We’ve redesigned mobile photo pages! Our new mobile photo pages have a look and feel consistent with the web-based photo pages and make it easier for your friends to interact with your photos when viewing them outside of Instagram on their mobile device.
When logged in, your friends can like and comment on your photos directly from their mobile web browser. They can also go directly from the mobile photo page into Instagram. Clicking on the Open in App button will automatically launch the Instagram app with the photo loaded into the main view. From there, users can navigate into your profile page and explore the rest of your photo feed.
