Question

@foreach (var orderline in order.OrderLines.DistinctBy(ol => ol.imageURL))
{
    <img height="40" src="@orderline.imageURL" alt="@(orderline.Listing.Title.Length > 15 ? orderline.Listing.Title.Substring(0, 15) : orderline.Listing.Title)" />
}

Answer 1

You are already using some Linq in your code, so just use a little more. The Take() method in Linq will do exactly what you want:

@foreach (var orderline in order.OrderLines.DistinctBy(ol => ol.imageURL).Take(5))
{
    <img height="40" src="@orderline.imageURL" alt="@(orderline.Listing.Title.Length > 15 ? orderline.Listing.Title.Substring(0, 15) : orderline.Listing.Title)" />
}

The Take(5) I added at the end means you will only iterate through a maximum of 5 items
