Use a ViewBox

<StackPanel HorizontalAlignment="Center" VerticalAlignment="Center">
    <Viewbox MaxWidth="500" MaxHeight="500" Name="vb1">
        <Image Source="tulip_farm.jpg"/>
    </Viewbox>    
</StackPanel>

How to: Apply Stretch Properties to the Contents of a Viewbox

Or you could use binding as below:

<StackPanel x:Name="MyStackPanel">
    <Image Source="C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg" Stretch="Uniform" Height="{Binding ElementName=MyStackPanel, Path=ActualHeight}"></Image>
</StackPanel>
