iPhone users who tweet photos will find much to like in the new version of the iOS Twitter app.
Released Wednesday, version 6.1 of Twitter for iOS adds several handy options for tweaking your photos before you share them with your followers. The gallery icon lets you quickly choose a photo from your camera roll. You can then crop and rotate it and view different versions of your photo as seen through different filters.
You can also select an existing tweet and then reply to it with a photo chosen through the gallery icon. And you can more easily mention the names of other tweeters when you add a photo to your own tweet.
