Tweetbot supports inline images from several different apps and services, including Instagram, which was disabled in the official Twitter app late last year following a dispute between Twitter and Instagram.
Videos shared from Vine and images shared from Flickr will now be shown directly within Tweetbot, without the need to open a separate window. Tweetbot includes native Vine controls that allow users to play videos via AirPlay and tweet links to videos.
Tweetbot's new version 2.7 update also includes the ability to open links in 1Password or Chrome, rather than Safari, and adds better support for muting Tweets that include URLs.
Both Tweetbot for iPhone [Direct Link] and Tweetbot for iPad [Direct Link] have been updated and can be downloaded from the App Store.
