Are you sure it's being served as image/jpeg?  That description sounds like it's
being served as text/plain.

When the page is open displaying ASCII characters, what does the "Type" field in
Page Info (Tools - Page Info) say?

The header "content-type: image/jpeg" was correct sent by server (IdHTTPServer).
snip:
"        ResponseInfo.ContentText := 'image/jpeg';
         IdHTTPServer.ServeFile(AThread, ResponseInfo, tmpFile);
"

1. Firefox display in Page Info: 
Address: http://localhost/
field type: text/html

2. Internet Explorer 6 display in Page Info: 
Address: http://localhost/
type: file HTM
------------------------------------------------------------------------

Opening the file (tmp.jpeg) with File - Open File:
1. Firefox display em Page Info: 
Address: file:///C:/tmp/tmp.jpg
field type: image/jpeg

2. Internet Explorer 6 display em Page Info: 
Address: file://C:\tmp\tmp.jpg
field type: Format Image JPEG

> 1. Firefox display in Page Info:

Then you're not sending the JPG as image/jpeg.  You're sending it as text/html,
so FF is trying to display it as such.  Check and fix your server's MIME types.
