One way is to use a word processing program that allows you to easily insert multiple pictures at different locations within the story. Just go to the 'Insert' option and choose the pictures you want to add. You can also resize and position them as needed.
You can use image editing software to combine the pictures first and then insert the combined image into the story.
Well, it depends on the platform or software you're using for your story. Some platforms have a straightforward 'Add Images' feature where you can select multiple pictures at once and place them where you want in the story. Make sure the pictures are of the right format and size for smooth insertion.
