Utilizing Selenium webdriver to retrieve images from the internet

Currently, I am attempting to retrieve images from a website using the following code snippet:

List <WebElement> listofItems = driver.findElements(By.cssSelector("div.heroThumbnails:nth-child(4) > div:nth-child(2) > div:nth-child(n)"));
URL imageURL = null;
for (WebElement myElement : listofItems) {
  String j = myElement.getAttribute("data-bigurl");
  System.out.println(j);
  for (int i = 0; i < listofItems.size(); i++) {
    try {
      // generate url
      imageURL = new URL(j);
      int countF = 0;
      // read url and retrieve image
      BufferedImage saveImage = ImageIO.read(imageURL);
      
      // save image in workspace with name picture.png
      ImageIO.write(saveImage, "jpg", new File(countF++ + ".jpg"));
    } catch (IOException e) {
      e.printStackTrace();
    }
  }
}

However, whenever the image is saved, it seems to overwrite the previous one. Is there a solution to prevent this issue? Any guidance on how to resolve this matter would be greatly appreciated. Thank you.

Perhaps you could find this useful:

ImageIO.write(saveImage, "jpg", new File(i + ".jpg"));

It seems like the issue might be that you are overwriting because you are giving them the same name.

To avoid this, you can either use a loop counter at the top or declare your countF variable outside of the loop:

int countF = 0;
for(int i = 0; i < listofItems.size(); i++) {
    try {
        // all your code here
        // ...

        // This will create an image with a new name each time
        ImageIO.write(saveImage, "jpg", new File(countF + ".jpg"));
        countF++;
    } catch (IOException e) {
        e.printStackTrace();
    }
}

I hope this solution works for you.

Happy Coding :)

Make sure to declare your countF variable outside of the loop so that its value is maintained across images.

    int countF = 0;
    for(int i = 0; i < listofItems.size(); i++){
        try {
            //generate url
            imageURL = new URL(j);
            //read url and retrieve image
            BufferedImage saveImage = ImageIO.read(imageURL);

            //download image to the workspace where the project is, save picture as picture.png (can be changed)
            ImageIO.write(saveImage, "jpg", new File(countF++ + ".jpg"));
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

On a side note: the code line new File(countF++ + ".jpg")); may seem a little messy with multiple plus signs in a row for incrementing inline. An alternative approach could be:

countF++;
new File(countF + ".jpg"));

However, this is simply a matter of personal coding style preference and either method should function correctly.
