how to get images on flask page

To get images on a Flask page, you can follow these steps:

  1. Import Flask and create an instance of the Flask class.
from flask import Flask
app = Flask(__name__)
  1. Create a route decorator using the @app.route() decorator. This will define the URL path for the route.
def home():
    return 'Home Page'
  1. In the route function, use the send_file() function from Flask to send the image file to the client.
from flask import send_file

def get_image():
    return send_file('path/to/image.jpg', mimetype='image/jpg')
  1. Save the image file in a folder within your Flask application directory. In this example, the image file is named "image.jpg" and is located in the "static" folder.

  2. In the HTML template, use the <img> tag to display the image. Set the src attribute to the URL of the image route.

<!DOCTYPE html>
    <title>Image Example</title>
    <img src="{{ url_for('get_image') }}" alt="Image">
  1. Run the Flask application.
if __name__ == '__main__':
  1. Access the Flask application in a web browser and navigate to the specified route, such as http://localhost:5000/image. The image will be displayed on the page.

Note: Make sure to replace 'path/to/image.jpg' with the actual path to your image file. Also, ensure that the image file is in a format supported by web browsers, such as JPEG or PNG.
