If you really wanted to, you could crop your panoramic photographs into multiple frames and post them strategically on Instagram so that your profile grid shows one photo in every row.
The problem with that is rarely to people go to profiles to look at photos.
The average Instagrammer will only browse their feed for recent and trending photographs.
That means your profile gets few views.
Instead, you should be using the Instagram Galleries feature, which creates a slider of up to 10 borderless photographs to one post.
Using this method makes the end result looks like a seamless panoramic. And the viewer doesn’t have to see what looks to be a broken image across multiple posts.
In the video below you will see how I go about it, and a demo of the free Photoshop Action I’ve created to speed up the task.
