There seems to be a problem with setting the signature file when copying the image address in the space album, but if you copy the image address in the post bar, it can be used as a signature file and the image will be displayed. I just copied the image address in my space album. The signature file cannot be set. Later, I sent the picture to the forum, then right-clicked, copied the image address, and then set the signature file. Pasted the long string of things in the signature file, and I found that the picture would be directly displayed. Then save it and wait for Baidu review
