how to display an image in the same page when we click an hypelinkfield in the gridview coloumn ?

Question

i have gridview in a page called scan.aspx .The gridview in the page scan.aspx contains a hyperlinkfield coloulmn. the hyperlinkfield coloumn displays an image no.When we click on the imageno(hyperlinkfield) the corresponding image with the imageno must be diplayed in a frame in the same page scan.aspx
--->  i.e first the page(scan.aspx) must display only the gridview and when user clicks the ----->hyperlinkfield then the    page(scan.aspx)  must display both the gridview and the image side by side

i am using C#.net and Asp.net(vs2005) with backend sqlserver 2000
