I think the most appropriate way to your solution is to store those images in the database field.
Then make a handler (.ashx) code file to handle the retrieving of such image. By then the indexing of your rows and columns in your grid is fix and is easily pin point.

Try to use, GridViewRowCommand event, with CommandName and CommandArgument.
I have given a similar type of answer over here,
CommandArgument in gridview asp.net[^]

you can use this..

C#

private void GridView1_Cell_Click(object sender, GridViewCellEventArgs e)
       {
           int cellindex=e.CellIndex;
           int rowindex =e.rowindex;
           var value = GridView1.Rows[rowindex].Cells[cellindex].value;
