DataGridView image column issue on sorting

I have a DataGridView that has an image column. The image address is read from one of the cells of the same row and then shown.

When I sort the columns the images go away.

I'm using Visual Studio 2010 and coding in C#. Data is retrieved from anaccess database using oledb methods.

Code that fills image columns is below: 

Image Image_File = Image.FromFile("d:\\2.jpg");

DataGridViewAutoSizeColumnMode.Fill; 

for (int i=0;i < info_Grid.RowCount;i++)  
{ 

   if (Info_Grid.Rows[i].Cells[6].Value !=" ")  
   {  
       Image_File =  Image.FromFile(Info_Grid.Rows[i].Cells[5].Value.ToString());  
       Info_Grid.Rows[i].Cells["Image_Col"].Value = Image_File;  
   }                                                                              
}  
Info_Grid.AutoSizeColumnsMode = DataGridViewAutoSizeColumnsMode.Fill;

How can I fix it?

Thanks

I know this is old, but I was troubled by this this morning. When sorting a dataviewgrid, all the images added at runtime are lost. Something about the built-in DataGridView sorting breaks this.

Example

DGV as Bound >> DGV after sorting

For me, I just added my image add code to the DGV.Sorted event. It somehow feels wrong to have to do this, but I do not know why these images are lost on sort in the first place.

  private void dgvChecks_Sorted(object sender, EventArgs e)
    {
        foreach (DataGridViewRow row in dgvChecks.Rows)
            {
                if (row.Cells["Valid"].Value.ToString() == "True")
                    row.Cells[0].Value = (System.Drawing.Image)Properties.Resources.check;
                else
                    row.Cells[0].Value = (System.Drawing.Image)Properties.Resources.delete;
            }           
    }
