Now with the fix :
All browsers shows a different thing, but not the image!

If I save it to computer :
* Windows image viewer won't read it
* Irfanview can read it without problems
Did you set the content-type and content-length in the HTTP headers?
Can you post your code?
I didn't know about content-lenght
Here's the new code (I used a fixed image patch to make sure this is not
the source of the problem)
#!/usr/bin/python3
import cgi, sys, cgitb
cgitb.enable()
f = open("/home/dodo/54.jpg", "rb")
data = f.read()
l = len(data)
f.close()
print("Content-type:image/jpg\nContent-length:%d\n\n" % l)
sys.stdout.flush()
sys.stdout.buffer.write( data )
Computers are dumb. You have to speak to them very slow and clearly in
order to be understood :)
You need a space after those ':'. The correct media type for JPEG images
is image/jpeg. And (the important thing) you have one more \n than
necessary. Each header field finishes with \n; an empty line (just \n)
marks the end of all headers; the body [your image] must follow
immediately.
#!/usr/bin/python3
import cgi, sys, cgitb
cgitb.enable()
f = open("/home/dodo/54.jpg", "rb")
data = f.read()
l = len(data)
f.close()
print("Content-Type: image/jpeg\nContent-Length: %d\n" % l)
sys.stdout.flush()
sys.stdout.buffer.write( data )
(Probably, a better way would be to replace all those \n with \r\n, and
not use print at all, but the above code is good enough).
