I have the following XAML structure:

<igRibbon:RibbonTabItem x:Name="ModuleLauncherTab"
                        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                        xmlns:igRibbon="clr-namespace:Infragistics.Windows.Ribbon;assembly=InfragisticsWPF3.Ribbon.v10.3"

                        Header="Launcher">
    <ItemsControl xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                  xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                  xmlns:igRibbon="clr-namespace:Infragistics.Windows.Ribbon;assembly=InfragisticsWPF3.Ribbon.v10.3">
        <ItemsControl.ItemsPanel>

            <ItemsPanelTemplate>
                <igRibbon:ToolHorizontalWrapPanel/>
            </ItemsPanelTemplate>
        </ItemsControl.ItemsPanel>
        <ItemsControl.ItemTemplate>
            <DataTemplate>

                <igRibbon:ButtonTool Caption="{Binding Name}"
                                     Command="{Binding Launch}"
                                     ToolTip="{Binding Description}"
                                     LargeImage="{Binding Image}"
                                     igRibbon:RibbonGroup.MaximumSize="ImageAndTextLarge"

                                     igRibbon:RibbonGroup.MinimumSize="ImageAndTextLarge"/>
            </DataTemplate>
        </ItemsControl.ItemTemplate>
    </ItemsControl>
</igRibbon:RibbonTabItem>

At run time button tools are added to the ItemsControl depending on the bound collection.

No matter what I try, the added buttons use small images (autoresized from 32x32) and caption on the right. How can I force the dynamically added ButtonTool instances to display large images and caption underneath instead?
