      preloadHDtime: false,
      placeHolderInside: true,
      iconZoomInEnable: true,
      percBigger: 25,
    }
	const fullImgAttr  = {
		srcSet: `ball.jpg 320w, ballBig.jpg 480w`,
		sizes: `(max-width: 320px) 280px, (max-width: 480px) 440px, 800px`,
		src: `ball.jpg`,
		alt: `this is cool`,
		// you can put other attributes...
	}
    
    <ImageZoomable imageAttr={fullImgAttr} options={options}>
        <img src="ball.jpg" sizes="(max-width: 320px) 280px" src-set="ball.jpg 320w"/>
    </ImageZoomable>

Options

preloadHDtime default = 0 It defines how much time in millisecond the component will wait before load a not visible version of full screen image. This can be useful is site host a large images (some megabytes), because probably when user click on the image, the full version is already loaded and user will not wait 10 second to download the image (thanks to cache) storybook-example

placeHolderInside default is false it defines if the colored loading will be inside the small image or cover the full screen window storybook-example

renderCustomPlaceholder undefined if this function is provided, the component will render a custom placeholder instead the original colored loading storybook-example

iconZoomInEnable default is false it defines if at the top-right corner of small image a zoom-in icon will be draw storybook-example

percBigger default is 10 storybook-example

debug default = false if true you can see a red line in full screen image. This is useful for development
