You can hook into the save pipeline of product and check the properties on the product and match up if they have the right image:

http://docs.ucommerce.net/ucommerce/v6/extending-ucommerce/create-pipeline-task.html

You can find the right properties by product["propertyName"].

Please note you want to do this on the variants collection since you uses variants.

so something like:

foreach(var product in Product.Variants) { ... }

Hope that helps you in the right direction.

Thanks Morten - i will give it a try :)

Hi Morten,

I am trying to do it in ucommerce.demostore.productpage.js and have the following function

function getProductImage(sku, color)
{  
    $.uCommerce.getProductVariations(
            { productSku: sku.val() },
            function (data) {

                $.each(data.Variations, function (i, v) {

                    var variationColor = getObjectsByKey(v.Properties, 'Name', 'Color')[0];
                    var variationImage = getObjectsByKey(v.Properties, 'Name', 'PImage')[0];
                    if (variationColor.Value == color) {                       
                        alert(color + " has " + variationImage.Value);                       
                    }
                });
                    success();
            },
            false
        );
};

when the variant proprerty color changes this function triggers. I am getting the ID of the variationImage but i don't know how to get the Image url for that ID. Do i need to make a webservice for that? or is there any other way to acheive it. 

I found a way to solve this by using the ImageUrl webservice from the following http://localhost:4089/ucommerceapi/json/metadata list

following is the code

$.ajax({
                            url: location.protocol + "//" + location.host + '/ucommerceapi/Content/ImageUrl/' + variationImage.Value
                        }).then(function (data) {
                            $('#imgColor1').attr('src', data);                          
                        });

There is one problem now. It doesn't work if i am not logged into the ucommerce backend. Can anyone help me?

Found a solution for the problem. I created a service class in the razor store and then called that service through Javascript.

is working on a reply...
