You can use image insertion tools or features provided by the platform you're using to add multiple pictures. Just look for the 'Insert Image' or 'Add Picture' option.
To insert multiple pictures in a story, first make sure you have the pictures saved and ready. Then, in most story editing software or apps, there'll be a specific button or menu for adding images. You might be able to drag and drop the pictures or browse your files to select them one by one. Just follow the prompts and instructions given by the software.
