When uploading to your feed, you’ll see a new icon to select multiple photos and videos. It’s easy to control exactly how your post will look. You can tap and hold to change the order, apply a filter to everything at once or edit one by one. These posts have a single caption and are square-only for now. On your profile grid, you’ll notice the first photo or video of your post has a little icon, which means there’s more to see.
In feed, you’ll see blue dots at the bottom of these posts to let you know you can swipe to see more. You can like and comment on them just like a regular post.
I like the idea of this, but its practical usability leaves a lot to be desired. If you swipe across a photo set from near the edge of the screen, it will switch to Instagram’s Story camera or its direct message view, depending on which way you swipe. And, if you swipe at the end of a photo set, you get moved into the direct message view as well, instead of bouncing back or looping around to the first photo.
