How to bind a local image file to an Image control in xaml?

First, thank you for your time.

My question is ultimately how to bind a local png file to an Image control on the xaml using the mvvm pattern and binding.  I am confused about whether to use:
1) <Image Source={Binding MyImage} .../>
2) <Image Source={Binding Path=MyImage} .../>
3) <Image>
            <Image.Source>
                  <BitmapImage UriSource="{Binding MyImageUri}" />
            </Image.Source>
     </Image>
4) Should I use my own converter or use Microsoft's ImageSourceConverter.

Will you please enlighten me?  Please show me the appropriate xaml code along with the corresponding c# code that will load the local png file from disk and make it appear in my view.

Thank you again for your time.

When you say "local", it sounds like you might want to get an image on the actual machine running the Silverlight, and you do not get access to the machine's file system.

If you mean local to your project, it depends on whether you have the image in there as content, embedded, etc.

Sorry, I didn't give you enough details about the project.  I am creating a Windows desktop application not an in-browser application.  So, I do believe I have access to the file system.

Again, thank you for your time.

Sorry, I should have figured this out from it being WPF rather than Silverlight!   Almost all of my XAML has been Silverlight rather than WPF.

With WPF you can just do

            image.Source = new BitmapImage(new Uri(@"file:///c:/users/jens/pictures/parkour.jpg"));

Thank you for responding yet again.

I followed your instructions and my image is still not showing.  Here is the code:

xaml:
       <ComboBox ItemsSource="{Binding Bills}" SelectedValue="{Binding BillSelected}" 
       <Image  Source="{Binding BillImageSource" />

c#:
        public ImageSource BillImageSource;

        // When a bill is selected from the combobox, this property is invoked with the bill that was selected. 
        public string BillSelected
        {
            set
            {
                var selectedBillName = value;
                var filename = _repository.GetBillFilenameByShortName(selectedBillName);
                var uri = new Uri(@"file:" + filename);
                var bitmap = new BitmapImage(uri);
                BillImageSource = bitmap;
                OnPropertyChanged("BillImageSource");
	    }
	}

Open in new window


As I step through the code, everything looks okay to me, and yet the png file that corresponds to the filename doesn't show.
What am I doing wrong?

Thank you for your time Jens.

Take a look at "filename"....does it look like this, like in my code?

///c:/users/jens/pictures/parkour.jpg

I'd be kind of surprised if it did, I think you might need to do some string munging to get this right.
