上一个博客中学习了如何在网页上进行简单的图片爬取，目的是制作一个简单的图片浏览器，然后可以选择喜欢的图片筛选到另一个文件夹中。

爬取图片的博客链接：[https://blog.csdn.net/yql\_617540298/article/details/112464575][https_blog.csdn.net_yql_617540298_article_details_112464575]

大体需要实现的功能就是选择一个文件夹，然后里面存放很多图片，然后可以查看图片，并进行“上一张”、“下一张”和“保存图片”的功能。

运行程序，选择指定的文件路径，然后可以查看图片。

选择文件夹后，可以查看第一张图片

选择指定喜欢的图片，点击“图片保存”，可以将其保存到另一个文件夹中。
