1. First send the picture to be signed to Baidu photo album and open your own photo album.

2. Click on the picture of the album, and this will happen.

3. Place the mouse on the picture and right-click an attribute option.

4. See the address bar? No, this is the specific address you want, which can be directly used as a signature document.

You see, the address is directly valid after you put it in the past, and it seems that you don't need the strange method upstairs.
