[SOLVED] Slow rendering of image in react Native


This Content is from Stack Overflow. Question asked by Wallace Nascimento

Image is downloaded , but still rendering very slowly, anyone knows what can be happening?

enter image description here

here is my code:

import React from 'react'
import { StyleSheet, Image, Text, View } from 'react-native'
import Backgroundimage from '../../../assets/images/backgroundImage.jpg'

export default function ImageContainer() {
return (
<View style={styles.ImageContainer}>
<Image source={Backgroundimage} style={styles.Backgroundimage}/>

const styles = StyleSheet.create({
ImageContainer: {
display: 'flex',
width: '100%',
justifyContent: 'center',
alignItems: 'center',
Backgroundimage: {
height: 450,
width: '100%',


2 reasons comes to my mind about why your images load slow.

1- Images are too large
The first thing you should do is optimize your heavy images, because larger-sized high resolutions can take up a lot of bandwidth from your end user.

2- Images have unspecified dimensions:
If you have an image that is 2500×2500 pixels, but you have scaled it down to 250×250 pixels, your app will have to load ten times more than necessary.
