 Hi,

<StackPanel  Grid.Row="1" Grid.Column="1" Background="RoyalBlue" Height="400"  ScrollViewer.VerticalScrollBarVisibility="Auto">

           <ItemsControl x:Name="lstPics" ItemsSource="{Binding}" Height="400" SelectionChanged="lstPics_SelectionChanged" ScrollViewer.VerticalScrollBarVisibility="Visible">
                <ItemsControl.ItemTemplate>

                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <StackPanel Orientation="Vertical">
                                <TextBlock Text="{Binding Path=FileName}" />
                                <CheckBox IsChecked="{Binding Path=IsSavedInServer}"  Content="exist in server" />
                        </StackPanel>
                        <Image Source="{Binding Path=ImageSource}"  Height="100" Width="150" Stretch="Fill" />
                    </StackPanel>
                    </DataTemplate>
                </ItemsControl.ItemTemplate> </ItemsControl >
        </StackPanel>

Put the

ScrollViewer.VerticalScrollBarVisibility="Auto"

For vertical scrollbar. Check the above code.
