Hi Stefani, I think this is because I downloaded the RealEstate Trial Demo - I think they thought I was new customer.
In regards to the question, I've discovered that if you just use a simple ImageControl then this appears to select the first image of the related data field. However, I'm not sure how to select the thumbnail rather than image using this control.
If the ImageControl cannot display the Thumbnail, I guess I'm going to have to use the ImageView, but filter the images shown based on a tag say ="First", in order to show just one image? I worry about how efficient this is?
