How to add image to datagrid in WPF with C#, i have stored the paths of images in database.
Design is like this:

----------------------------------
Name| Roll| Marks|Image
--------------------------------
A   | 1    |90   |img1.jpg
B   | 2    |80   |img2.jpg

*******************************************
I am using this to fill the data into dataGrid:

dataGrid2.ItemsSource = ds.Tables["Table1"].DefaultView;

DataGrid  SelectionMode="Extended"  SelectionUnit="Cell" IsReadOnly="True"  Name="dataGrid2" VerticalAlignment="Top" Height="147" Margin="26,130,63,0" AlternatingRowBackground="#FFAE65AE" AreRowDetailsFrozen="True" AlternationCount="0" AutoGenerateColumns="False" Background="{x:Null}">
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Name}"  Header="Name"  />
 <DataGridTextColumn Binding="{Binding Roll}"  Header="Roll"  />
 <DataGridTextColumn Binding="{Binding Marks}"  Header="Marks"  />
               
                <DataGridTemplateColumn Header="Image">
                    <DataGridTemplateColumn.CellTemplate>
                        <DataTemplate>
                            <Image Height="10" Width="10" Stretch="Uniform"  >  </Image>
                        </DataTemplate>
                    </DataGridTemplateColumn.CellTemplate>
                </DataGridTemplateColumn>
            </DataGrid.Columns>
        </DataGrid>
