Introduction

0:00	One of the most important parts of your workflow is getting your images and videos into the Cloudinary Media Library. In this tutorial, you'll learn how to use the Go SDK to upload one or multiple images to Cloudinary.

Upload a single image from your local file system

Once the Cloudinary Go module is installed, imported, and configured, you can upload local images from your directory. Start by creating a context with context.Background() and save it to the variable ctx. Then call the Cloudinary uploader method, passing the image path as an argument. Make sure to reference the correct path in your file system. Save the upload response in a variable and add proper error handling. Finally, print out the response as formatted JSON for easy reading.

Upload response

Upload multiple images from your local file system

To upload multiple files efficiently, first define their file paths in an array, then use a Go loop to iterate over this array. Inside the loop, place the Cloudinary uploader code and replace the static image path with the loop variable that represents the current image path. Be sure to add proper error handling to catch any issues during the upload process. This approach ensures each image in the array gets uploaded successfully. For cleaner output, instead of printing the entire upload response for each image, you can log only the secure URLs.

Upload a single image from a remote URL

While we've covered uploading images from your local directory, Cloudinary's uploader is versatile and accepts images from other sources as well. You can upload images directly from remote URLs, allowing you to pull images from other servers directly into your Cloudinary account. The process is straightforward: simply replace the local image path with a web image URL in your uploader call. When you run the code, it returns the Cloudinary delivery URL for the uploaded image, which you can then open in a browser to verify the successful upload.
