JSON Question

Populating drop down with json object

I have managed to populate my drop down menu with a json object, which worked fine.
Currently I am trying to display an image which is in a hidden div based on an option selected from the drop down. As the drop down is populated by the json object how would I retrieve the image data.

Html

<form>
<fieldset id="autoHeight">
<legend>pod</legend>
<h2>Cars</h2>
<select name="drop_down" id="dropDownCars">
<option value="None" selected="Selected">Select type</option>
</select>
</fieldset>
</form>
<div id="showBmw" class="hidden">
<a href="http://cdn.iphoneincanada.ca/wp-content/uploads/2012/08/white-bmw.jpg"></a>
</div>


JSON File

{
Cars: [{
"CarType": "BMW",
"carID": "bmw123"
}, {
"CarType": "mercedes",
"carID": "merc123"
}, {
"CarType": "volvo",
"carID": "vol123r"
}, {
"CarType": "ford",
"carID": "ford123"
}]
}


This is how I populate the dropdown menu using jquery.

$(document).ready(function() {
$.getJSON("../cars.json", function(obj) {
$.each(obj.cars, function(key, value) {
$("#dropDownCars").append("<option>" + value.carsName + "</option>");
});
});
});


Any working example in jfiddle, would be very much appreciated! Thanks.

Answer
$('#dropDownDest').on('change', function() {
    if ($(this).val() == 'vol123r') {
        $('#imghide').removeClass('hide');
    } else {
        $('#imghide').addClass('hide');
    }
});
