Above you will notice that I have a simple ASP.Net GridView. The last column has an ASP.Net LinkButton lnkSelect to select the GridView Row and find its RowIndex as well as the Bound Fields and Template Fields.
When the Select LinkButton is clicked, I first identify the GridView Row and then using it I find the column values as well as access the controls inside the Template Fields.

GRIDVIEW ZOOM IMAGE

When you have images in your  GridView , you would most likely show them as thumbnails so as to not distort the whole layout.
