"not able to do that" - what happens? What error messages do you get? Or
does nothing happen?

What is the scope of $image? Have you recognized it as a global within the
function, and declared it external to the function?

Have you deconstructed randomImage and built it up incrementally within
function.php?

Could it be that if you try and include it in functions.php there is output
somewhere sent to the browser before the header() and session_start()
functions are called?

Finally, what's wrong with calling it as you do at present? Flash
programmers are forced into that model for every class they create. It must
be an independent .as file, with the same name as the function, and contain
code only for properties and methods of that function.
