Nowadays, most of our time is basically wasted on browsing the web. There are many media resources on the web, the most common of which are pictures. When we browse to better websites, we can't help but want to download pictures when we see better-looking pictures. Generally speaking, we right-click the icon and select save image as, select the location to save, and then save. Don't be so naive to think that you have already downloaded a picture. In fact, it is not. When you find that there are too many downloaded pictures, you will inevitably feel that this method is extremely inefficient. And when a large number of images are downloaded, they have to be classified manually, which is extremely troublesome.
Here I would like to recommend an efficient way to download images - crawler crawling and automatic download. If you understand the principle of crawling, you can also apply the same method to the download of video, audio and text resources.
Here I directly recommend a small program for crawling pictures. Interested readers can modify this small program for crawling articles and so on.
