Solution 1

<HierarchicalDataTemplate.Triggers>
    <DataTrigger Binding="{Binding IsExpanded}" Value="True">
        <Setter TargetName="treeImg"
                Property="Source"
                Value="Images/vsfolder_open.png"/>
    </DataTrigger>
</HierarchicalDataTemplate.Triggers>

and obviously one for False as well.
