Since you tagged this question with Silverlight v4.0, I will assume that you are trying to accomplish this in said technology. One way to accommplish this would be to add a converter as a static resource and then use said converter to pull in the data. For all intensive purposes, I am assuming that the image files are named with in the format imageX.jpg, where X is equal to the score, but you can use whatever format you prefer. Please see below a untested, sample of XAML and C# code:
<USERCONTROL.RESOURCES>
<UserControl.Resources>
<SvcTest:DSTest x:Key="DSTest" d:IsDataSource="True"/>
<local:IDToImageConverter x:Key="IDToImageConverter"/>
</UserControl.Resources>
<UserControl.Resources>
<StackPanel x:Name="OurStack" Orientation="Vertical">
<TextBox x:Name="InputText"/>
<TextBlock x:Name="OutputText"/>
<Button x:Name="CallServiceButton" Content="Call WCF" Click="CallServiceButton_Click"/>
<data:DataGrid x:Name="theDataGrid" AlternatingRowBackground="Beige" Grid.Row="2" Grid.Column="1" Height=" 600" Width="800" CanUserResizeColumns="True" AutoGenerateColumns="False">
<data:DataGrid.Columns>
<data:DataGridTextColumn Header="InventTypeID" Width="100" Binding="{Binding InventTypeID}" />
<data:DataGridTemplateColumn Header="ImageColumn" DisplayIndex="1" >
<data:DataGridTemplateColumn.CellTemplate>
<DataTemplate>
<Image Source="{Binding ItemID, Converter={StaticResource IDToImageConverter}}" Height="50" />
</DataTemplate>
</data:DataGridTemplateColumn.CellTemplate>
</data:DataGridTemplateColumn>
</data:DataGrid.Columns>
</data:DataGrid>
</StackPanel>
<?xml:namespace prefix = local /><local:IDToImageConverter x:Key="IDToImageConverter"></local:IDToImageConverter>
</USERCONTROL.RESOURCES>
public class IDToImageConverter : IValueConverter
{
public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
{
Uri uri = new Uri("~/Images/" + value.ToString()+ ".jpg", UriKind.Relative);
return new BitmapImage(uri);
}
<GRID Background="White" x:Name="LayoutRoot">
<STACKPANEL x:Name="OurStack" Orientation="Vertical">
<TEXTBOX x:Name="InputText" />
<TEXTBLOCK x:Name="OutputText" />
