Example:

Returns a JPEG image with the headers:

HTTP/1.1 200 OK
Date: Wed, 08 Mar 2006 18:11:12 GMT
Server: Apache/2.2.0 (Unix)
Connection: close
Content-Length: 37534
Content-Type: image/jpeg

The embedded resource parser incorrectly guesses the content type as 'application/octet-stream' based on the filename 'preview'. Confluence is then unable to render it.

When the filename guessing provides no useful content type for external resources, the parser should check the content-type HTTP header.
