# Selfie best-practices

If you're using our Android SDK, we take care of image quality with our unique [SmartSelfie™ capture](http://bit.ly/GreatSelfies). Furthermore, iOS devices have consistently strong camera hardware and thus generally results in good quality images for us to process.

However, if you choose to capture images without the use of one of our SDKs we strongly encourage you to provide your users an example of best practices for image capture.

**A few rules for uploading selfie images**

* We suggest a resolution of `480x640` for selfie images and `240x320` for liveness images.
* Keep the total payload size (selfie and liveness images and job metadata) under `10 megabytes` before submission.
* If individual images are > 10mb, your job might not be processed successfully.
* We support `Jpeg` image files, and `BASE64` encoded image strings depending on the product endpoint.

**Show your users how to take the perfect Selfie**

## 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://legacy-docs.usesmileid.com/further-reading/faqs/what-are-good-selfie-best-practices.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.
