Extract images from playwright page without requesting them again?

Let's say I've requested a page and it's fully loaded. Is it possible to save the images from the rendered/loaded page without sending another request for the image? This would be to avoid just collecting the individual image urls and hammering the server for each image again.

In case someone else comes here with the same problem:

Mine is a dynamic GIF, so a screenshot won't help much.

I therefore solve this by intercepting image requests made while loading the page like this (adapted from a blog post on the topic):

from playwright import sync_playwright

def on_response(response):
  if not response.ok:
    return  # if you don't want to ignore errors, add error handling here
  if response.request.resource_type == "image":
    with open(PATH_TO_STORE_IMAGE_AT, "wb") as f:
      f.write(response.body)

with sync_playwright() as p:
  browser = p.chromium.launch()  # or firefox or webkit
  page = browser.new_page()
  page.on("response", on_response)
  page.goto(URL_OF_PAGE_CONTAINING_IMAGE)

This could be fleshed out a bunch but should demonstrate the overall idea.

transfer this to python code.

byte[] slideBg = page.locator("xpath=id(\"slideBgWrap\")").screenshot();
ByteArrayInputStream inStreambj = new ByteArrayInputStream(slideBg);
BufferedImage newImage = ImageIO.read(inStreambj);
ImageIO.write(newImage, "jpg", new File(url + "outputImage.jpg"));
