[RESOLVED] Slider

[HowTo]

i just binded the slider with an image so that when i am sliding the slider,then the image will enlarge or shrink (Sorry for not using the proper terms but i am sure that one using the wpf can understand what i am trying to say)

here is what i did:

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525">
    <StackPanel>
        <Slider x:Name="imageslider" Minimum="100" Maximum="500" Width="200"></Slider>
        <Image Source="Untitled.jpg" Width="{Binding ElementName=imageslider,Path=value}" Height="{Binding ElementName=imageslider,Path=value}" HorizontalAlignment="Center" Stretch="None" DataContext="{Binding}"></Image>
    </StackPanel>
</Window>

unfortunately when i am sliding the slider,then the image is not enlarging or shrinking

any help please?
