 # Advanced Usage
 
-## Service
-
-The `responsive-image-local` service provides the available images (local privider) with the sizes for a given origin image, and retrieves the image that fits for the current screen size.
-
-```js
-let availableImages = responsiveImageService.getImages('myImage.png');
-/**
-availableImages contains now: 
-[
-    {width: 640, height: 320, image: "/assets/images/responsive/myImage640w.png"},
-    {width: 750, height: 375, image: "/assets/images/responsive/myImage750w.png"},
-    ...
-    {width: 2048, height: 1012, image: "/assets/images/responsive/myImage2048w.png"}
-]
-*/
-
-let imageData = responsiveImageService.getImageDataBySize('myImage.png', 100); // The size argument is in ´vw´, 100 is the default and can be omitted
-// {width: 750, height: 375, image: "/assets/images/responsive/myImage750w.png"}
-
-let fittingImage = responsiveImageService.getImageBySize('myImage.png', 100); // The size argument is in ´vw´, 100 is the default and can be omitted
-// "/assets/images/responsive/myImage1080w.png"
-```
-
-The base width to calculate the necessary image width is the `screen.width` assigned to the `screenWidth` property of the services. If this doesn't fit your needs, you can assign an other value, e.g. `document.documentElement.clientWidth`.
-
 ## Helper
 
 The `responsive-image-resolve` helper provides the image url that fits for the current screen size. The first parameter is the name of the origin image.
