I have been in this situation before. After 0.0, I am like this.
Just find a post in the dialog box.
Add a picture. You know QVQ. Add the desired picture as a signature file to the dialog box.
Then right-click the picture and click Properties.
The picture address appears, yo-ho, that's right. Copy this thing just like copying a website!
Then set the signature file and paste the URL as above. It will never appear red.
///A// If red appears, you must be mistaken. . . . . . .
