Bottle python how to display a picture inside a template

When working with the Bottle framework in Python, you may come across the need to display a picture inside a template. There are several ways to achieve this, and in this article, we will explore three different options.

Option 1: Using the static_file() function

The static_file() function in Bottle allows you to serve static files, such as images, from a specified directory. To display a picture inside a template, you can use this function to serve the image file and then reference it in the template.

from bottle import Bottle, static_file, template

app = Bottle()

@app.route('/static/')
def serve_static(filename):
    return static_file(filename, root='path/to/image/directory')

@app.route('/')
def index():
    return template('index.tpl')

app.run()

In the above code, we define a route to serve static files from a specified directory using the static_file() function. Inside the template, you can reference the image using the URL generated by the static_file() function.

Option 2: Using base64 encoding

Another option is to encode the image file as base64 and embed it directly in the template. This eliminates the need to serve the image as a separate file.

import base64
from bottle import Bottle, template

app = Bottle()

def encode_image(image_path):
    with open(image_path, 'rb') as image_file:
        encoded_image = base64.b64encode(image_file.read()).decode('utf-8')
    return encoded_image

@app.route('/')
def index():
    image_path = 'path/to/image.jpg'
    encoded_image = encode_image(image_path)
    return template('index.tpl', image=encoded_image)

app.run()

In this code, we define a function encode_image() that reads the image file, encodes it as base64, and returns the encoded image as a string. Inside the template, you can use the encoded image directly by passing it as a variable.

Option 3: Using a CDN

If the image you want to display is hosted on a Content Delivery Network (CDN), you can simply reference the image URL in the template. This option is suitable when the image is already available on a CDN and you don’t need to serve it from your application.

from bottle import Bottle, template

app = Bottle()

@app.route('/')
def index():
    cdn_image_url = 'https://cdn.example.com/image.jpg'
    return template('index.tpl', image=cdn_image_url)

app.run()

In this code, we directly pass the CDN image URL as a variable to the template. The template can then use this URL to display the image.

After exploring these three options, the best choice depends on your specific requirements. If you have control over the image files and want to serve them from your application, Option 1 using the static_file() function is a good choice. If you prefer embedding the image directly in the template, Option 2 using base64 encoding is a viable option. Finally, if the image is already hosted on a CDN, Option 3 is the simplest solution.

    1. I completely disagree. Option 2 is far superior. Encoding is a small price to pay for efficiency and flexibility. #TeamOption2

    1. I couldnt disagree more! Option 3 is the way to go if you want to step up your game. Option 2 might be simple, but wheres the excitement? Dont settle for mediocrity, my friend. Embrace the fanciness and capture those breathtaking moments! 🌟📸
