Hi, how would you get the below to work exactly as it does but to also change a picture for each different selection e.g. 1 picture if you select 140mm x 300mm, a different picture if you select 140mm x 400mm and a different picture again if you select 140mm x 500mm? many thanks in advance.

I'd be inclined to add the extra data as data- attributes on the <option> tags. That way, you keep the data together, and you won't forget to update the array when the list changes.

HTML

<select id="theList">
    <option value="" data-price="Please Select a Size to Show Price" data-image="http://placehold.it/150x150">--Select One--</option>
    <option value="1" data-price="£10" data-image="http://placehold.it/350x150">Item 1</option>
    <option value="2" data-price="£20" data-image="http://placehold.it/150x350">Item 2</option>
</select>

<p>Price: <span id="priceText"></span></p>
<p>Image: <img id="theImage" src="data:image/gif;base64,R0lGODlhAQABAAD/ACwAAAAAAQABAAACADs=" /></p>

<script>
var updateSelectedDetails = function(){
    var opt = $("#theList").find("option:selected");
    $("#priceText").text(opt.data("price"));
    $("#theImage").prop("src", opt.data("image"));
};

$("#theList").change(updateSelectedDetails);
updateSelectedDetails();
</script>
