I have a usercontrol which displays colour swatches depending on whether or not the colour has been selected using a true/false datatype.
A colour is actually an ImageButton and when I click the button I need an Image to change to reflect the color.

I am using a switch statement (because there is potentially more than one colour)

ImageButton img = (ImageButton)sender;
string prodImgToDisplay = string.Empty;
switch (img.ID)
    {
        case "imgBtnColGlossBlack":
        this.ltlColorImage.Text = prodImgBlack;
        break;
    }

and this is working fine when I run it in Visual Studio.

My problem is, getting the path of the image into the variable prodImgBlack. I have tried the following but it still only returns the image id.

<umbraco:Macro field="umbracoFile" nodeid="[#prodImgBlack] prodImgBlack="[#prodImgBlack]" Alias="ProductImages" runat="server"></umbraco:Macro>

In my full code I will be specifying more than one image parameter in the macro. Is anyone able to help me out?!

Thanks,

Rachel
