I wish people didn't keep trying to write CGI in 2014.

To redirect in a plain CGI application, you just need to output the destination next to a "Location:" header. However, you have already closed the headers and printed a blank HTML document at the top of your script. Don't do that: it's not only wrong for the redirection, it's also wrong for your alternative path, the form error, since you have already closed the HTML tags.

Instead, start your script like this:

# No printing at the start!
import cgi
...

try:
    form = cgi.FieldStorage()
    fn = form.getvalue('picture_name')
    cat_id = form.getvalue('selected')
except KeyError:
    print "Content-type: text/html"
    print
    print "error"
else:
    ...
    if response.status == 200:
        print "Location: response.php"
