3. Move the mouse to Personal Settings on the right side of the interface, and click Signature File Settings in the personal settings bar. You can modify the signature file name and picture link in the pop-up dialog box. Click "Submit" to edit successfully.

It's the third one. No?

First, look at the picture link and do it.

Then the link to the picture you copied should look like this:

/album/xxxxxxx/sign = xxxxxxxxxxx . jpg

If you restrict the use of post bars and spaces, the text is still red.

/photo album/. . Just change the letters in brackets.

take for example

g.hiphotos.baidu.com/album/s%。 . . . . . .

change into

a.hiphotos.baidu.com/album/s%。 . . . . . .

If not, change it to b, c, d, and so on. .

If the above is not enough, just give me the picture and I will send you a link to do it.
