### Introduction
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=00 :player=cld} | Svelte is a modern JavaScript framework designed for building web applications, with SvelteKit providing a convenient option for constructing full-stack applications. [Svelte Cloudinary](https://svelte.cloudinary.dev/) enables developers to manage and optimize the media files in their applications.
|

### More about Svelte Cloudinary
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=0 :sec=23 :player=cld} | Svelte Cloudinary provides access to components for optimizing and modifying media files, and enabling client-side media uploads. Additionally, Cloudinary provides a Node.js SDK for server-side integration with Svelte applications, particularly useful for managing image uploads in scenarios like user forms. This video tutorial focuses on setting up and utilizing the Svelte SDK within an existing Svelte application.
|

### Install and configure Svelte Cloudinary
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=04 :player=cld} | The first step is to install Svelte Cloudinary using `npm install svelte-cloudinary`. Once installed, set your environment variable for Cloudinary in your `.env.local` or `.env` file using the format: `VITE_PUBLIC_CLOUDINARY_CLOUD_NAME="[Your Cloud Name]"`. Find your **Cloud name** on your [Cloudinary Dashboard](https://console.cloudinary.com/app/home/dashboard). 
|

### The CldImage component
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=23 :player=cld} | Now, you can start using Cloudinary. Let's focus on the `CldImage` component. Import it using `import { CldImage } from "svelte-cloudinary"`, and in your app, instead of using the standard image tag, use `CldImage`. For the source, pass a public ID of the image. In this example, the public ID for a Cloudinary image is "demo/red-sneaker". 
|

```svelte
<CldImage src="demo/red-sneaker" alt="Color pair of sneakers"/>
```

### Setting width and height properties
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=46 :player=cld} | You also need to define the width and height properties to avoid layout shift. This setup ensures optimized images, with the image format tailored to the device, reducing file size significantly.
|

```svelte
<CldImage 
  width={960}
  height={600}
  src="demo/red-sneaker" 
  alt="Color pair of sneakers">
/>
```

### Image optimization
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=1 :sec=50 :player=cld} | Open the Network tab and refresh your page to check the format and size of your image, with and without the `CldImage` component. You'll notice that when you use `CldImage`, your images are smaller and use the format that's optimal for the requesting browser.
|

### Use CldImage to display multiple images
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=2 :sec=23 :player=cld} | Use the following sample code to render multiple images with Svelte Cloudinary's `CldImage` component.
|

```svelte
<div class="images_list">
  {#each products as product (product["public-id"])}
    <div class="images__item">
      <CldImage 
        width={960}
        height={600}
        src={product["public-id"]}
        alt={product.alt}
      />
      <span class="images__item__unsplash">
        {product.unsplash}
      </span>
    </div
  {/each}
</div>  
```

### Remove background
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=2 :sec=30 :player=cld} | You can leverage different Cloudinary features with the `CldImage` component. For instance, using the remove background feature. 
|

```svelte
<div class="images_list">
  {#each products as product (product["public-id"])}
    <div class="images__item">
      <CldImage 
        width={960}
        height={600}
        src={product["public-id"]}
        alt={product.alt}
        removeBackground
      />
      <span class="images__item__unsplash">
        {product.unsplash}
      </span>
    </div
  {/each}
</div>  
```

### Overlays
{table:class=tutorial-bullets}|  | 
| --- | --- |
|{videotime:id=media :min=2 :sec=45 :player=cld} | Other features include [overlays](layers), such as adding text watermarks to images. Check the [CldImage Configuration](https://svelte.cloudinary.dev/cldimage/configuration/) page for acceptable properties and values.
|

```svelte
<div class="images_list">
  {#each products as product (product["public-id"])}
    <div class="images__item">
      <CldImage 
        width={960}
        height={600}
        src={product["public-id"]}
        alt={product.alt}
        overlays={[
          {
            text: {
              text: "Brand",
              color: "white",
              fontFamily: "Poppins",
              fontSize: 100,
              fontWeight: "black",
            },
            effects: [{
              opacity:50
            }]
          }
        ]}
      />
      <span class="images__item__unsplash">
        {product.unsplash}
      </span>
    </div
  {/each}
</div>  
```
