How to Link Images from Outside of Your Next.js Project Folder

Creating a web application often involves displaying images, especially when users upload their products. If you’re working with Next.js, Node.js, and Express, you may run into issues when trying to link to images stored outside your Next.js project folder. This guide will guide you through the solution step by step.

The Problem

When you're developing a project that includes image uploads, organizing your files correctly is crucial. Currently, you have your image uploads stored in a folder named uploads outside the Next.js project directory. This results in the error: "could not load the image." Here’s a quick recap of your folder structure:

In your Next.js code, you are referencing the image path as /uploads/image-name.png, but since the image is not located in the public directory of the Next.js app, it does not load correctly.

The Solution

To solve this problem, you need to move your uploads directory into the public directory of your Next.js application. This allows your application to serve static assets like images directly from the public folder. Here’s how you can do it:

Step 1: Restructure Your Project

Update your folder structure so that the uploads directory is inside the client/public directory:

Step 2: Update Your Image Path

Once you have moved the uploads directory, update the image path in your Next.js components to point to the images correctly. Your new image path will look something like this:

Why This Works

Next.js uses the public directory to serve static files at the root of your application. By placing your uploads folder inside public, you ensure that Next.js knows where to look for these files, thus preventing the "could not load the image" error.

Conclusion

Properly organizing your project structure is essential for seamless development in Next.js. By moving your uploads directory into the public directory, you can effectively link images from outside your Next.js project folder, ensuring your application runs smoothly. Don’t forget to adjust your image paths accordingly to avoid any loading issues.
