Default Behavior: When using Zip upload in a media tree that has a start node other than root and a user upload a Zip file of images (or other files) the zip file creates a folder in Media/{zipfile_name.zip}.

Issue: The user will never see the uploaded folder/files since they do not have access to the root media node. 

Solution:

<script type="text/javascript">
    $(document).ready(function(){
        // event handlers...
        // click on a client
        $('#ctl00_body_dashBoardZipUpload_Button1').click(function(){
            var value=$('#ctl00_body_dashBoardZipUpload_Panel1 a').html();
            if (value=='Choose...') {
                alert('Please select a folder to upload your files in. If you don\'t have any folders, please create one in the "Media" root to the left.');
                return false;
            }
        });
    });
</script>

It's crude and rudimentary, but without editing the source, this seemed like a good shortcut. Hope it's of use to others as well. Nibble, I hope I am not "stepping on your toes" adding this to the forum. Thanks for a great package!
