|{videotime:id=media :min=0 :sec=00 :player=cld} | SolidJS is designed for speed, and it's crucial that your images load just as quickly. Learn how to utilize Cloudinary's URL-Gen SDK to set up, optimize, and transform images in SolidJS.

### Use the Cloudinary URL-Gen SDK in SolidJS

|{videotime:id=media :min=0 :sec=17 :player=cld} | The Cloudinary URL-Gen SDK is versatile and can be integrated into any JavaScript app or framework. To use it with SolidJS, install the SDK, import it into your project, and then set up a new Cloudinary instance. Begin transforming Cloudinary URLs by updating your existing image `src` prop to `{cld.image(<public id>).toURL()}`.

### Apply Cloudinary optimizations

|{videotime:id=media :min=1 :sec=12 :player=cld} | Optimize your images by chaining the `quality` option with the value "auto" for [Automatic Quality Selection](image_optimization#automatic_quality_selection_q_auto). Then, chain the `format` option, also set to "auto," for [Automatic Format Selection](image_optimization#automatic_format_selection_f_auto).

### Add image transformations
{table:class=tutorial-bullets}|  |

|{videotime:id=media :min=1 :sec=56 :player=cld} | Enhance your image optimization by adding transformations. Import the `scale` action and chain the `resize` transformation to set the image width to 1200px and height to 800px. You can take this a step further by utilizing Cloudinary's [Responsive Images](responsive_images) solution.
