Well, either write the sql code twice, or could break out all your
database queries into functions which you then put in a php file (say
db_funs.php). Now require("db_functions.php") at the top of your file
and call the get_navbar_image () when you need it. You also need to
require("db_functions.php") in the "include file depending on url" file.
The general philisophy is thus to put all programming logic which you
use more than once in separate functions which you include.
