[Jerry Ai]

When i use the function of upload by CKEditor, the picture can not show but Firefox.

Reason： Picture where the server uses used prevent hotlinking, Google Chrome cann't send "Referer" in headers information.

Request Headers with Google Chrome. Request Headers with Firefox.

1. Whether to send Referer header or not its browser or other client decision. You can't force it.
2. This header can be blocked by software for security reasons.
3. There are also ways to remove such header or change it

I think that what you need is changing your rules - if there is no Referer header allow and not block.
