Introduction In this tutorial, we will learn how to upload and display an image on a website using JavaScript. We will be creating a profile card with a default profile image and a button to update the image. Upon clicking the button, a window will open allowing us to select an image file, which will then be displayed on the profile card.

Setting Up the HTML and CSS Files Before we can begin creating the image upload and display functionality, we need to set up the HTML and CSS files. This involves creating a folder for our project and adding the necessary files, including an HTML file, a CSS file, and a folder for storing the images.

Creating the Profile Card To create the profile card, we will first add a div with the class name "hero" to our HTML file. This div will serve as the container for our profile card. Next, we will add a div with the class name "card" within the hero div. Inside the card div, we will add an H1 tag for the user's name and a P tag for some text content.

Adding the Default Profile Image In order to display a default profile image on the profile card, we will add an IMG tag within the card div. We will set the file path of the image to the path of the default profile image file. Additionally, we will apply CSS styles to the image to set its width, height, border radius, and margin.

Designing the Image Upload Button Next, we will create an input field of type "file" to allow users to select an image file for upload. To design the upload button, we will add a label element with a for attribute referencing the input field. We will apply CSS styles to the label to give it a visually appealing appearance.

Implementing Uploading Functionality In order to make the image upload button functional, we need to add JavaScript code. We will use the onchange event of the input field to trigger a function that updates the source of the profile picture image element with the selected image file. This function will utilize the URL.createObjectURL method to generate a URL for the selected image file.

Displaying the Selected Image Once the user selects an image file, we will display the selected image on the profile card. This will be done by updating the src attribute of the profile picture image element with the URL of the selected image file.

Testing the Image Upload and Display Feature To test the image upload and display feature, we will open the website and click on the "Update Image" button. This will open a window allowing us to select an image file. After selecting an image file, the selected image should be displayed on the profile card.

Conclusion In this tutorial, we have learned how to implement image uploading and displaying functionality on a website using JavaScript. This feature allows users to update their profile pictures easily. By following the steps outlined in this tutorial, you can incorporate image upload and display functionality into your own web projects.
