using XAML to bind to a System.Drawing.Image into a System.Windows.Image control

I'm binding a ListView to a list of objects, like so;

<ListView 
    ItemsSource="{ Binding Path=. }"
    ItemTemplate="{DynamicResource EventTemplate}">   

I'm binding to an object which declares two properties;

string DisplayName { get; }
System.Drawing.Image Image { get; set; }

I want to populate a DataTemplate but I can't figure out how; if I do this in my template;

<StackPanel Orientation="Horizontal">
    <Image Source="{ Binding Path=Image }" />
    <TextBlock Text="{ Binding Path=DisplayName }" />
</StackPanel>      

The text appears but the image does not. What am I doing wrong? The debug output shows

System.Windows.Data Error: 1 : Cannot create default converter
to perform 'one-way' conversions between types
'System.Drawing.Image' and 'System.Windows.Media.ImageSource'.
Consider using Converter property of Binding.
BindingExpression:Path=Image; DataItem='RealElement'
(HashCode=54308798); target element is 'Image' (Name='');
target property is 'Source' (type 'ImageSource')
