Users can upload photographs and short videos, follow other users' feed  and geotag images with the name of a location.  Users can connect their Instagram account to other social networking sites, enabling them to share uploaded photos to those sites.  In January 2011, Instagram introduced hashtags to help users discover both photos and each other. Instagram encourages users to make tags both specific and relevant, rather than tagging generic words like "photo", to make photographs stand out and to attract like-minded Instagram users.  In September 2011, a new version of the app included new and live filters, instant tilt–shift, high-resolution photographs, optional borders,

 one-click rotation, and an updated icon In August 2015, Instagram started allowing users to upload full-size landscape and portrait photos and videos onto the service, dropping the previous requirement of a square frame. In September 2016, Instagram removed Photo Maps, which previously allowed users to see a map of their geotagged photos. An Instagram spokesperson stated that "Photo Map was not widely used, so we've decided to remove the feature and focus on other priorities".  In December 2016, Instagram introduced a feature letting users save photos for later viewing. Bookmarked posts get added to a private page in the app.  The feature was updated in April 2017 to let users organize saved posts into different collections^.  In February 2017, Instagram announced that users would be able to upload up to ten pictures or videos to one post, with the content appearing as a swipeable carousel. In May 2017, Instagram updated its mobile website to allow users to upload photos, and to add a "lightweight" version of the Explore tab   Later in May, Instagram added an "Archive" feature, letting users hide posts in a private storage area, out of visibility for the public and other users. The move was seen as a way to prevent users from deleting photos that don't garner a desired amount of "likes" or are deemed boring, but also as a way to limit the "emergent behavior" of deleting photos, which deprives the service of content.
