Hello, the signature file only supports Baidu Post Bar Picture Library and Baidu Space Pictures.

The method is as follows:

1. You can upload the picture to my space photo album first, or post it in the photo album.

Then go to Baidu Space Album or Post it Album, find the picture you want to set, right-click the picture properties, and click the "copy address" option in the options above the picture when copying the link. It is wrong to copy the "website" directly.

3. Then enter Baidu Post Bar and my I Post Bar. Move the mouse to Personal Settings on the right side of the interface, and click Signature File Settings in the Personal Settings bar to modify the name and picture link of the signature file in the pop-up dialog box. Click "Submit" to edit successfully. I hope I can help you.
