Django Return Images to Frontend Guide

There are typically two ways to return images to the frontend in Django.

1. Displaying images in HTML pages using template language: Using the syntax of Django template language in HTML pages, we can set the image URL as the value of the src attribute in order to display the image on the page. Here is an example code:

<img src="{{ image_url }}" alt="Image">

In the view function, we need to pass the URL of the image to the template for rendering. Example code is shown below:

from django.shortcuts import render

def image_view(request):
    image_url = "/path/to/image.jpg"
    return render(request, "image.html", {"image_url": image_url})

1. Directly return the binary data of the image: In the view function, you can directly return the binary data of the image by using the content_type attribute of the HttpResponse object to set the MIME type of the image. Example code is shown below:

from django.http import HttpResponse
import os

def image_view(request):
    image_path = "/path/to/image.jpg"
    with open(image_path, "rb") as f:
        image_data = f.read()
    
    return HttpResponse(image_data, content_type="image/jpeg")

The above are two common options, and the specific choice depends on the requirements and design of the project.
