If you have a list of pictures you can place a panel (StackPanel, WrapPanel, etc., depends on the behaviour you want) inside a ListBox. Set the panel to be the items host, and set the list of pictures as the ItemsSource. Something like this:

<ListBox x:Name="_listBox" >
    <ListBox.ItemsPanel>
        <ItemsPanelTemplate>
            <WrapPanel Orientation="Horizontal" IsItemsHost="true" />
        </ItemsPanelTemplate>
    </ListBox.ItemsPanel>
</ListBox>

and then in the code behind set _listBox.ItemsSource to your list of pictures.

(or you can have your list of pictures in an ObservableCollection and bind the ListBox to it)

EDIT: as for the thumbnails you can use something like:

BitmapImage Picture = new BitmapImage();
Picture.BeginInit();
Picture.UriSource = ... // your picture
Picture.DecodePixelWidth = ... //how big you want your pic
Picture.EndInit();
