You have a couple of options:
You could add an optional parameter to the function that handles the click,
like this:
function clickThumb(e:MouseEvent,index:int = 0):void{
}
Setting a default value for the index parameter allows the function to be
called without passing it. That's what will happen when a thumb is clicked.
When you want to call the function directly, you'd do:
clickThumb(null,image_num + 1);
In clickThumb, check whether the event object is null or not. If it's not,
do what you're currently doing. If it's null, use the index parameter as the
index into my_images.
Another thing you could do is a bit of refactoring.
Have the click handler only resolve the index and calling another function
to actually load the image.
function clickThumb(e:MouseEvent):void {
loadImage(e.target.name);
}
function loadImage(index:int):void {
if (my_full_images[index] == undefined){
var full_url = my_images[inde...@full;
... etc ...
}
Then, from your other button's handler, call loadImage(image_num + 1);
