  Not too hard, the plumbing would be just having <IMG> tag or <asp:Image> in DataGrid's ItemTemplate and its src or ImageUrl attribute points to the URL to that handler/page. That's how it works because external resources (such as images) need to fetched with separate HTTP request from the HTML/markup itself.
  
  E.g. You link to the custom page /hander which processes the request and generates the image from given parameters, from <IMG> / Image control.

  If that given code runs on imagegenerator.aspx without any querystring parameters given to the URL
  
  It would be
  
  <asp:TemplateColumn>
     <ItemTemplate>
        <asp:Image ID="image" runat="server" ImageUrl="imagegenerator.aspx" />
      </ItemTemplate>
  </asp:TemplateColumn>
  
  E.g as I explained on previous post, due to working of HTTP, the page where IMG tag resides fetches it from the given page (fetching actually happens by the browser, with separate requests, one for each image)
