## Example

In this example, we will take a photo using a mobile device and view the photo in the image component.

### Steps

1. Drag an `image` and a `button` component to a page in the mobile designer.

   ![](/files/GHpAmV1YPQou7UsGPDdP)
2. Select the event `press` for the button and drag the function `Device.captureImage` to the event flow. Fill in the parameters of the function.

   ![](/files/zRYFedIx1uiyYXmDyTYv)
3. Drag the the function to be executed if the image is captured successfully to the node below the function. In this example, we are using the `App.setComponentValue` to set the image to the image component. Fill in the parameters of the function.

   ![](/files/Ad8sksL2iAIKrT6lBpeh)

### Result

1. The image captured will be shown in the image component.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.emobiq.com/emobiq-client/006-actions-and-visual-logic/action-reference/react-native/device/captureimage.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
