Instagram have just pushed through some changes to its mobile photo pages affecting both design and function. Design-wise, we're looking at a more consistant look and feel with its Web-based counterpart. In the function department, the developer has made it easier for users to interact with their photos, as well as friends' photos when viewing them outside of the Instagram app itself, but still on a mobile device.
Instagram updated their Web presence which paved the way for comments and likes on a few months ago, something they call "the new Photo Page". The latest update to the photo-taking and sharing application looks to move the old mobile site's design to the recently-launched desktop site.
The mobile version now lets Instagram users like and comment on photos from their chosen mobile web browser, and it now lets you go directly from the mobile photo page into the Instagram app by tapping the "Open in App" button. Tapping the Open in App button will launch the Instagram app, with the photo you were on previously, loaded into the main view.
