Having trouble with datepicker options

Having trouble with datepicker options

I don't know why, but the datepicker always trips me up.
I've set up a datepicker with the following settings:
        $(".datepicker").datepicker({
            dateFormat: 'yyyy-mm-dd',
             appendText: '<span class="inputNote"> (yyyy-mm-dd)</span>',
            buttonImageOnly: 'images/icon_datepicker.gif',
            changeMonth: true,
            changeYear: true,
            yearRange: '-150:+10'
        });
3 questions:
1) When I pick a date, the text field gets filled in with a double
year. For instance, if I pick 1999-10-12, the field is then filled in
as '19991999-10-12'. Any idea why?
2) I can't get the icon to show up at all. In relation to the page
that shows the datepicker, the image *is* located in
'images/icon_datepicker.gif'. Any way to easily debug that issue?
3) yearRange. Is there a way to fix the first year but make the second
relative? I tried "1900:+10" but it doesn't seem to like that mix of
fixed and relative options.
