Adding image previews to your file uploads enhances the user experience by letting users visually confirm their selected images before uploading. To achieve this with FilePond, you need to include the image preview plugin and register it with FilePond. This involves adding the plugin's CSS and JavaScript files to your HTML, then calling FilePond.registerPlugin() with the plugin object. Once registered, FilePond automatically displays thumbnails for image files that users select. This immediate feedback helps users avoid mistakes, such as uploading the wrong image, and makes the upload process more intuitive and visually appealing.
