To fix image not showing in React Native and JavaScript, we set the source prop to the correct value.
For instance, we write
<Image
source={{ uri: "https://picsum.photos/400/300" }}
style={{ width: 400, height: 400 }}
/>
to add an Image component with the source prop set to { uri: "https://picsum.photos/30/30" } to display the image at the URL.

Sometimes, we want to add transparent overlay in React Native and JavaScript.
In this article, we’ll look at how to add transparent overlay in React Native and JavaScript.
To add transparent overlay in React Native and JavaScript, we add transparent styles for the View.
For instance, we write
import { View, StyleSheet } from "react-native";
const styles = StyleSheet.create({
overlaycontainer: {
...StyleSheet.absoluteFillObject,
backgroundColor: "#000",
opacity: 0.8,
justifyContent: "center",
alignItems: "center",
},
});
//...
<View style={styles.overlaycontainer}>
<Text style={{ color: "#fff" }}>Locating directions please wait ...</Text>
</View>
to add styles with the opacity value with StyleSheet.create.
Then we use the styles.overlaycontainer styles for the View.

Sometimes, we want to fit Image in containing View, not the whole screen size with React Native.
In this article, we’ll look at how to fit Image in containing View, not the whole screen size with React Native.
To fit Image in containing View, not the whole screen size with React Native, we set resizeMode to cover.
For instance, we write
const style = StyleSheet.create({
imageStyle: {
alignSelf: "center",
height: "100%",
width: "100%",
},
});
//...
const Comp = () => {
//...
return (
<View>
<Image
style={styles.imageStyle}
resizeMode={"cover"}
source={item.image}
/>
</View>
);
};
to add an Image with the resizeMode prop set to cover.
This will make it fit to the View wrapped around it.
