There are a few ways to do this, but the most common way is to use the Instagram app’s “post” feature. This allows you to add multiple photos, with different sizes, into one post. To start, open the Instagram app and click on the three lines in the top left corner of the screen. This will take you to a menu where you can select “post.” On the “post” menu, select “photos.” In this menu, you’ll see a list of photos that have been uploaded to Instagram. You can click on any of these photos to view it in detail. If you want to post a photo with a different size than what is available on your phone’s camera lens, you can use one of Instagram’s filters. To do this, open Instagram and click on the three lines in the top left corner of the screen again. This time, select “filters.” In this menu, select “photo filter.” Then choose an option that will change how your photo looks when posted online. For example, if you want your photo to look like it was taken with a large phone camera lens, choose “large phone camera lens.”
