external js file and repeated function

[craigtaylor74]

Hi,
I would like to take the following function out of my xhtml page and link to it via an external js file.
In most cases I know how to do this but this function is repeated on many pages BUT with different 'variables' (I never know the right word!).
This is what I have on my pages at the moment (each using different images):

function makeArray() {
this.length = makeArray.arguments.length
for (var i = 0; i < this.length; i++) this[i+1] = makeArray.arguments[i]
}
var teams = new makeArray ("images/products/boston_compact1.png", "images/products/boston_compact2.png");
var eatMe = 1;
function flipper() {
document.form.image.src = teams[eatMe];
eatMe += 1;
if (eatMe == 3) eatMe = 1;
setTimeout("flipper()", 4000);
}

So, the images are different from page to page... how can I prepare these functions to be put in one external file and take account of the different images used?
Can I make them:
function makeArray1()
function makeArray2()
function makeArray3() etc. ?


Thanks for any ideas,
Craig
