Displaying Images based on column value in WPF datagrid

I have a datatable queried from SQL server table.
The data table contains only one column, it will have numbers from 0 -9.
I need to display that in WPF datagrid. I have done displaying as ordinary datagrid.
But I need to display a separate picture and some text for that specific number in that column.
Is it possible thorugh Datagrid?

Use DataGridTemplateColumn and bind it using an IValueConverter that will transform your int into an ImageSource

Here is a small working example :

MainWindow.xaml

<Window x:Class="StackOverflow.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:sys="clr-namespace:System;assembly=mscorlib"
        xmlns:local="clr-namespace:StackOverflow"
        Title="MainWindow" Height="350" Width="525">

    <Window.Resources>
        <local:IntToImageConverter x:Key="IntToImageConverter" />
    </Window.Resources>

    <DataGrid>

        <DataGrid.Columns>
            <DataGridTemplateColumn>
                <DataGridTemplateColumn.CellTemplate>
                    <DataTemplate>
                        <StackPanel Orientation="Horizontal">
                            <Image Source="{Binding Converter={StaticResource IntToImageConverter}}" />
                            <TextBlock Text="Image number : " Margin="5, 0, 0, 0" />
                            <TextBlock Text="{Binding}" Margin="5, 0, 0, 0" />
                    </StackPanel>
                    </DataTemplate>
                </DataGridTemplateColumn.CellTemplate>
            </DataGridTemplateColumn>
        </DataGrid.Columns>

        <sys:Int32>0</sys:Int32>
        <sys:Int32>1</sys:Int32>

    </DataGrid>

</Window>

MainWindow.xaml.cs

using System;
using System.Windows;
using System.Windows.Data;
using System.Windows.Media;
using System.Windows.Media.Imaging;

namespace StackOverflow
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }
    }

    public class IntToImageConverter : IValueConverter
    {

        public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            ImageSource result = null;
            var intValue = (int)value;
            switch (intValue)
            {
                case 0:
                    {
                        result = new BitmapImage(new Uri(@"your_path_to_image_0"));
                        break;
                    }

                case 1:
                    {
                        result = new BitmapImage(new Uri(@"your_path_to_image_1"));
                        break;
                    }
            }
            return result;
        }

        public object ConvertBack(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
        {
            throw new NotImplementedException();
        }
    }
}
