Well, to add screenshots to a story, first make sure the screenshots are clear and relevant. Then, depending on the platform or software you're using, there are usually options like 'insert image' or 'upload picture' that you can use to incorporate the screenshots into your story. Also, consider the placement and context to make it blend smoothly.
Adding screenshots to a story isn't too hard. You need to have the screenshots saved on your device. Then, when writing the story, look for an option like 'add image' or something similar. Select the screenshot from your saved files and it'll be included. Just make sure it enhances the story and doesn't clutter it up.
