React Js Multiple Image Upload with Preview
React Js Multiple Image Upload with Preview:Reactjs is a popular JavaScript library used for building user interfaces. To implement multiple image upload functionality with a preview in React.js, you can follow a few steps. First, create an input field with the "multiple" attribute to allow multiple file selection. Next, handle the onChange event to capture the selected files and store them in state.
Then, map through the selected files and create image previews using the FileReader API. Finally, render the image previews in the component's UI. This approach enables users to select and preview multiple images before uploading them, enhancing the user experience in React.js applications.

How can I implement multiple image upload with preview in ReactJS?
This code snippet demonstrates a Reactjs component that allows users to upload multiple images with a preview feature. The component maintains state using the useState hook, which includes an array of images, a boolean showModal to toggle a modal window, and selectedImage to store the currently selected image.
When a file is selected using the file input, the handleFileUpload function is triggered. It reads each file using the FileReader API, converts it to a data URL, and adds it to the images array with the corresponding file and preview URL.
The component renders a container with a file input and an image container. Each uploaded image is displayed as a div with the preview image and a remove button. Clicking on an image triggers the showImage function, which sets the selected image and shows the modal window.
The modal window displays the selected image and includes a close button. Clicking on the close button or anywhere outside the modal closes it.
