How to Dynamically Load Images in a React App: A Complete Guide

In the world of web development, images play a crucial role in enhancing user experience. However, developers can often face challenges when it comes to loading images dynamically in a React application. If you've recently encountered issues such as being unable to load images using relative URLs, you are not alone. In this guide, we'll explore the problem in detail and provide you with effective solutions to load images dynamically in React.

Here, you're using a relative URL for the images located at ../../assets/images/imageName.jpg. While this approach might work in CSS files, you may find it failing in your JSX code. This inconsistency can leave you frustrated as you try to figure out the right way to display your images.

The Solution: Correctly Importing Images

1. Using Imports for Static Images

The standard approach to load images in React is to import them directly from the specified folder. Webpack handles the underlying conversion when you import images this way. Here’s how you can do it:
