How to preview multiple images before uploading it to server?

Previewing multiple images before uploading them to the server can be achieved using JavaScript and the HTML5 FileReader API. Here's an example:

  1. Add an input element for file selection: In your HTML file, add an input element with a type of file and the multiple attribute that allows the user to select multiple image files:
  1. Add an image container element: Add a container element to your HTML file that will be used to display the previews of the selected images:
  1. Attach a change event to the input element: In your JavaScript file, attach a change event to the input element that triggers when the user selects files:
  1. Implement the previewImages function: Implement the previewImages function that uses the FileReader API to read the selected image files and add image elements to the image container element to display the previews:

By following these steps, you should be able to preview multiple images before uploading them to the server. The image previews are achieved by using the FileReader API to read the contents of the selected image files and adding image elements to the image container element to display the previews.
