Upload pictures to Flickr via Windows File Explorer

Flickr is a very practical Web 2.0 service. Basically, the pictures on my blog are stored on Flickr, which can greatly reduce the server's traffic load and effectively prevent issues like image hotlinking. Therefore, Flickr is one of the Web 2.0 services I use the most frequently. Previously, I published a comprehensive collection of Flickr tools, listing many useful third-party Flickr tools. In fact, the official Flickr site also provides many useful tools; it's just possible that we haven't paid special attention to them. For example, this tool allows you to upload images via Windows File Explorer. You don't need to install any software to quickly and conveniently upload images in bulk.
