How to show image files from a directory in a flipview? - image

Question

I found many samples of displaying images from a resource in a Windows Store app and got it to display images within a sample, but I would require the flipview to show images in a directory, or at least to show image file names I provide by code. With everything I tried so far the flipview remains empty. I maybe missing something obvious, this is the relevant part of the XAML:
<FlipView x:Name="flipView1" HorizontalAlignment="Center" VerticalAlignment="Center" Margin="809,350,9,7" Width="548" Height="411" >
<FlipView.ItemTemplate>
<DataTemplate>
<Image Source="{Binding Path=Image }" Stretch="Uniform"/>
</DataTemplate>
</FlipView.ItemTemplate>
</FlipView>
this works, but it requires me to add the images a resource first....
ImageBrush brush1 = new ImageBrush();
brush1.ImageSource = new BitmapImage(new Uri("ms-appx:///Assets/P1000171.jpg"));
FlipViewItem flipvw1 = new FlipViewItem();
flipvw1.Background = brush1;
flipView1.Items.Add(flipvw1);
but (for example) this doesn't:
string name = String.Format(#"c:\temp\P1000171.JPG");
Uri uri = new Uri(name);
BitmapImage img = new BitmapImage(uri);
flipView1.Items.Add(img);
What do I miss?

In the meantime I've found the answer myself which I now add for future readers. The above example won't work because a Windows 8 app isn't allowed to access most of the PC's directories without the user having selected one using a FolderPicker. The program can re-use that directory later with:
StorageApplicationPermissions.FutureAccessList.AddOrReplace("PickedFolderToken", folder);
I've changed the above XAML here:
<Image Source="{Binding}" Stretch="UniformToFill"/>
The Task below will show all .JPG files in the Pictures library in a Flipview, if, in the Package.appxmanifest, Capabilities, "Pictures library" has been checked:
public async Task flipviewload()
{
IReadOnlyList<StorageFile> fileList = await picturesFolder.GetFilesAsync();
var images = new List<BitmapImage>();
if (fileList != null)
{
foreach (StorageFile file in fileList)
{
string cExt = file.FileType;
if (cExt.ToUpper()==".JPG")
{
Windows.Storage.Streams.IRandomAccessStream fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
using (Windows.Storage.Streams.IRandomAccessStream filestream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read))
{
BitmapImage bitmapImage = new BitmapImage();
await bitmapImage.SetSourceAsync(fileStream);
images.Add(bitmapImage);
}
}
}
}
flpView.ItemsSource = images;
}
