Network images require you to set height/width style props.

React Native Documentation.

Many of the images you will display in your app will not be available at compile time, or you will want to load some dynamically to keep the binary size down. Unlike with static resources, you will need to manually specify the dimensions of your image.

// GOOD
<Image source={{uri: 'https://facebook.github.io/react/img/logo_og.png'}}
       style={{width: 400, height: 400}} />

// BAD
<Image source={{uri: 'https://facebook.github.io/react/img/logo_og.png'}} />
