Take the Douban stills of Haijie Diary as an example. If you want to download a clearer original image, you have to get the link of the original image, and then use Thunder to download in batches.
The link of the still image is as follows: https://movie. douban.com/subject/25895901/photos?type=S&start=0&sortby=vote&size=a&subtype=o
first in the browser, use Ctrl+S to save all the files on the page,
and then find the webp file inside,
and then in bash, get The original links to all the pictures,
for f in *.webp; do echo https://img2.doubanio.com/view/photo/raw/public/${f/webp/jpg}; done
Just paste the link into Thunder,
