You can leverage the GridView’s DataKeys property for this:

<asp:GridView ID="gvImages" runat="server" AutoGenerateColumns="False" DataKeyNames="CustomerID">

In your code you can loop through the rows and read the data key for that row and get the checkbox like this:

foreach (GridViewRow gvr in gvImages.Rows)
{
    int CustomerID = (int)gvImages.DataKeys[gvr.RowIndex].Value;
    CheckBox CheckBox1 = (CheckBox)gvr.FindControl("CheckBox1");
}
