There is no need to compress it. Is it because you set it wrong?

You send the picture to be signed to Baidu Space Album.

Then enter the photo album and open the picture.

Click on the operation in the upper right corner.

The originally copied link can be used as a signature file.

But there are bugs in the post bar system these days.

Just change the "bdimg" in the link to "Baidu".

hope this helps
