Programatically Displaying image in gridview

I have a table that returns a column with 1 and 0. I wish to display a redx.gif if the column returns a 0, and a greencheck.gif if the column returns a 1.

I have determined I can use the rowdatabound to read the column value. Can someone tell me how I can add an imagefield column and assign it the proper gif per the returned result.
 Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles GridView1.RowDataBound
           If e.Row.RowType = DataControlRowType.DataRow Then
            Dim cell As TableCell
            cell = e.Row.Cells(2)                              ("2 Is the column with the returned data")
            If CDbl(cell.Text) = 0 Then
               cell = e.Row.Cells(3)                            ("3 is the imagefield column")

"HOW DO I ASSIGN THE GIF IMAGES TO THE CELL HERE?"

               
            End If
        End If
    End Sub

You'll have to get a handle to the image control by using cell.FindControl(ImageControlName).  Once you get that, you can set the ImageURL property.  If you post your markup, I can give you the exact code snippet.

for your example, by far the easiest solution would be to save 0.gif as a red x and 1.gif as your green check and then just add an imagefield control to the gridview with the datafield being that which returns the 1 or 0 and dataformatstring="{0}.gif"

or you could even loop through your gridview and for every 0 it finds in that particular cell, it changes it to "redx.gif" and for every 1 to "greencheck.gif" or something like that. programmatically adding an image field just seems like a brute force method for something that's otherwise really simple.
