Blurred image loading

To have a blurred image placeholder when loading, you have to pass the image to the minifiedSrc prop. For better UX use minified low-quality copies of the original image.

import React from 'react'
import Reimage from 'reimage';
import * as minifiedImage from './path/to/minified;' // importing minified image

export default function Blurred() {
  return (
    <Reimage
    crossOrigin='anonymous'
    src={src}                          // can be URL or imported image
    width={400}
    height={500}
    minifiedSrc={minifiedTest}         // pass minifiedImage to component            
    alt="oops"
    classNames="ClassName1, ClassName2, ClassNameN"
    wrapper="div"
    wrapperClass="customWrapperClassName"
  />
  )
}
  

Colored backdrop on image loading

To have a coloured backdrop on the load you just have to specify color you want in prop backDropColor.

import React from 'react'
import Reimage from 'reimage';

export default function BackdropColored() {
  return (
    <Reimage
    crossOrigin='anonymous'
    src={src}
    width={400}
    height={500}
    alt="oops"
    classNames="ClassName1, ClassName2, ClassNameN"
    wrapper="div"
    wrapperClass="customWrapperClassName"
    backDropColor='#e3e3e3'      
  />
  )
}
  

Handling error on image loading

If your image is not loaded for some reason you can handle this in several ways:

1) Specify errorImage and show image,

2) Specify altAsError and show text from the alt attribute as an error in the image container.

Note: Don`t choose two error-handling methods at the same time. errorImage have more priority then altAsError, so when checked both showed will be only errorImage.

import React from 'react'
import Reimage from 'reimage';
import * as errorImage from './path/to/error;'

export default function HandleErrors() {
  return (
    <Reimage
    crossOrigin='anonymous'
    src={src}
    width={400}
    height={500}
    alt="oops"
    classNames="ClassName1, ClassName2, ClassNameN"
    wrapper="div"
    wrapperClass="customWrapperClassName"
    errorImage={errorImage}                               (1)
    altAsError={true}                                     (2)
  />
  )
}
  

Loading image with fallback

To add fallback to your image just specify prop fallbackComponent and optionally provide styles for it with fallBackWrapperStyles.

import React from 'react'
import Reimage from 'reimage';
import * as originalImage from './path/to/original;'

export default function BackdropColored() {
  return (
    <Reimage
    crossOrigin='anonymous'
    src={src}
    width={400}
    height={500}
    alt="oops"
    classNames="ClassName1, ClassName2, ClassNameN"
    wrapper="div"
    wrapperClass="customWrapperClassName"
    fallbackComponent={<Spinner />}
    fallBackWrapperStyles={{ position: 'absolute', zIndex: 2, left: '15%', top: '15%' }}
  />
  )
}

In addition to provided props you can use default image attributes such as alt, crossOrigin etc.
