If there is nothing wrong with the way you copy the image link, it is a problem with Baidu Tieba.
Look carefully at the picture link you copied and replace "bdimg" with "baidu" in the link.
This is a Baidu bug, go try it!
I wish you success!
I am very happy to answer your question. If you are satisfied, please accept it. Thank you!
