1. Get the SRC attribute of the image.
2. Use ImageIO.read to read the image onto a BufferedImage
3. Save the BufferedImage using ImageIO.write function

String src = imgElement.getAttribute('src');
BufferedImage bufferedImage = ImageIO.read(new URL(src));
File outputfile = new File("saved.png");
ImageIO.write(bufferedImage, "png", outputfile);

 WebElement logo = driver.findElement(By.cssSelector(".image-logo"));
 String logoSRC = logo.getAttribute("src");

 URL imageURL = new URL(logoSRC);
 BufferedImage saveImage = ImageIO.read(imageURL);

 ImageIO.write(saveImage, "png", new File("logo-image.png"));

JavascriptExecutor js = (JavascriptExecutor) driver;                              
String base64string = (String) js.executeScript("var c = document.createElement('canvas');"
                       + " var ctx = c.getContext('2d');"
                       + "var img = document.getElementsByTagName('img')[0];"
                       + "c.height=img.naturalHeight;"
                       + "c.width=img.naturalWidth;"
                       + "ctx.drawImage(img, 0, 0,img.naturalWidth, img.naturalHeight);"
                       + "var base64String = c.toDataURL();"
                       + "return base64String;");
String[] base64Array = base64string.split(",");

String base64 = base64Array[base64Array.length - 1];

byte[] data = Base64.decode(base64);

ByteArrayInputStream memstream = new ByteArrayInputStream(data);
BufferedImage saveImage = ImageIO.read(memstream);

ImageIO.write(saveImage, "png", new File("path"));
