IU 6.5.x Java - Event Handler

The event(s) I am looking for triggers are:

ADD file to upload pane

REMOVE file from upload pane

<script type="text/javascript">
    function imagedAdded(){
        ... do stuff here;
    }

    function imagedRemoved(){
        ... do stuff here;
    }
</script>



<?php
    $imageUploader = new ImageUploader("ImageUploader1", 650, 400);

    $imageUploader->addedImageToUpload("imagedAdded");
    $imageUploader->removedImageToUpload("imagedRemoved");
    
    $imageUploader->render();
?>

Are there event triggers for adding/removing files to the upload pane? ? Maybe I am overlooking them in the docs in looking at the names?

We only use the Java control, 6.5.x, last version before the 7.x series (7 is a major code rewrite for us right now), on LAMP servers. Mix of clients users from Linux to win.

I need to do some thing on the page when the user adds/removes an file(image) from the upload pane. Prefer if it can work with other file formats as well as we use the control for non image uploads like PDF and some custom formats...

Thanks for assistance in advance.
