sending images via socket?

[rainlet]

I wrote a simple server in Python. It works well when sending HTML
file. But the browser will display image in a text form ( many strange
ASCII code ). I read the image files in the way :

FD = open ( FILE, "rb" )

and I send this also :

NEWSOCK.send ( "Content-Type: image/" + FILETYPE )

Can anyone tell me what's wrong?

Thank you very much!
