Yes Dave so we need to remove <img src="/data/images/mail.png">  since the apache cant see to open it and let Python open it which we know it can because it has access to any system file the user has access too.

httpd cannot open this file because the location of the image is past the addon domain's Document Root.

/home/nikos/public_html/cafebar-idea.gr = Addon's Domain Document Root

/home/nikos/public_html/data/images/mail.png = where the image file is located

and the python scipt is on:

/home/nikos/public_html/cafebar-idea.gr/cgi-bin/counter.py

So if a python script can open any file the user has access too then we need a "python way" of opening this file.

What are you trying to accomplish?  I don't see how opening the file
with python will do anything because as has been said many times on this
thread, your python CGI generates html code which the browser then
renders.  Opening an image file with python will do nothing useful.

Still don't understand why you want python to open the image file.  What
do you want python to do with it?  It's running on a web server, so
there's no screen for python to display the image too.

Technically it is possible to have a script that opens the image and
serves it up as a binary stream to the browser using the image
content-type header, but it's way more efficient to serve up the file
statically.  And you'd have to have a proper link in the html code
anyway, to refer to your image-serving CGI script.

Methinks you're barking up the wrong tree with python opening the image
file.

Yes, iam using this and it works.
One last thing:

my python script file is located at /home/nikos/public_html/addon_domain/cgi-bin/

How python is able to run the following statement?

f = open( '/home/nikos/public_html/' + page )

which is clearly levels up of addon domain's DocumentRoot?

$ export DOCUMENT_ROOT=${HOME}/public _html

Then from python os.environ['DOCUMENT_ROOT'] will have the relative path.

I hope this helps.

Not it's not.  There is nothing in the operating system that defines this.

> is there avariable for that? i can't seem to find any...

Not there's nothing in the operating system that specifies this.  This
is a convention that makes sense only to the apache daemon itself.  If
your python script is running as a CGI script, then apache will set
environment variables that you can read with the os module.  See the
Apache docs for information on this.

Is this link generated by your python CGI script?  If so you'll have to
work out some way for your python script to interact with Apache and ask
it where the document root is.

If this link is in static html, then you simply need to fix your html to
make the link valid.  Or maybe you need to modify your apache
installation so that it knows where "/data" is using an alias directive
in your apache config.

So why don't you put the image at  /home/nikos/public_html/cafebar-idea.gr/data/images/mail.png?

Yes my Python scripts exist in a linux web host.

os.environ['HOME'] will indeed give the home directory of the user.

to me /home/nikos/

but i want a variable to point to

/home/nikos/public_html whice is called DocumentRoot.

is there avariable for that? i can't seem to find any...

In the general case it is not possible. There is no single convention you can use to detect the top of a web site.

If you always use apache httpd then read the value of DocumentRoot from httpd.conf

The main ways we handle something like this are:

1. Set an environment variable that Python then reads to get the
DocumentRoot value.
2. Use something like zc.buildout to produce both your httpd.conf and
create a config file containing the value of DocumentRoot.
