Forward/ back button for various sub-folders

Question

Hello all,
Here's the scenario.....
I have a forward and back button that load several images in a sub-folder that load to a UIloader....
next_btn.addEventListener(MouseEvent.CLICK, nextImage);
function nextImage2(evtObj:MouseEvent):void{
imageNumber++;
LargeImageLoader.source = "portfolio/UIloader/bike/00"+imageNumber+".jpg";
checkNumber();
back_btn.addEventListener(MouseEvent.CLICK, backImage);
function backImage2(evtObj:MouseEvent):void{
imageNumber--;
LargeImageLoader.source = "portfolio/UIloader/bike/00"+imageNumber+".jpg";
checkNumber();
Since I have multiple sub-folders for my portfolio, I was wondering how to apply these same buttons to other sub-folder image paths without needing to create a pair of forward/back buttons for each sub-folder.
Thanks!

It's not entirely clear to me, but what I think you need to do for what I think you are saying you want to do would be to make the folder targeting (portfolio/UIloader/bike/, et al) a variable as well.  The only missing link is what you would use to redefine the folders.
Your next/prev buttons can't be that smart unless you have some conditional logic that helps them realize a particular imageNumber range belongs to a particular folder.  If your images have the same file names (00#.jpg) across the different folders then that won't help.  I believe you would need them to be sequential such that no folder repeats the filenames/numbers of another
