Web Forms :: Showing Images From A SQL Database With A GridView?

I'm trying to show images that come from a sql query into a GridView column, the problem is that the best solution found in the web searches the database twice for each row.

This solution says that we have to first create a handler (ImageHandler.ashx),

It will receive the ID of the row that contains the image, and then query the database with that ID.

Then it will finally perform something like "context.Response.BinaryWrite((byte[])dReader["Photo"]);" (in this case the handler uses a DataReader, I guess we could use another approach)

We also have to declare the image column in the markup as:

<asp:TemplateField HeaderText="Image">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# "ImageHandler.ashx?ID=" + Eval("ID")%>' />
</ItemTemplate>
</asp:TemplateField>

The problem is that, the Grid is bound to a SqlDataSource with a SelectCommand like: "Select ID, Name, Photo FROM Employees", that is already querying the database, then the GridView will execute the handler with the ID in it's query string, so the handler will query the database again for the same row, to extract the image.

Isn't there a way to send the image to the handler, so that it only performs the instruction "context.Response.BinaryWrite..." without having to query the database again?
