Image is broken in Knowledge Article

[Community Alums]

After cloning is done, image is broken in Knowledge Article.

I observed that attachments are missing from Article. So I have exported attachments from sys_attachment table of higher instance where issue is not there and imported in lower instance where issue is there.

Yet issue is not resolved.

Images are still not appearing.

When I downloaded attachments, Format is as below

Suggest me what needs to be done.

I'd first try to add a extension and update the kb to use the file.  So if it's a jpeg, .jpg, or .png, or .gif.

I got solution for this issue. I have imported both sys_attachment and sys_attachment_doc records for the particular article from other instance, then images started appearing.
