hi all!!

i'm writing functions like - 
function top () {
 echo "blah blah blah";}

what i want to do is make it so that i can do - 
function top($image) {
 echo "blah blah $image blah"; }

but also make the $image parameter in the top() as optional. so if
its not there, then tell php not to worry about it.

any ideas??
