ASP.net VB.net Set dimensions of image field in GridView

Hi
I have an ASP.net GridView with an image field where the dimensions are set
Is it possible to store these dimensions in two of my SQL table
columns as I have the DataImageURL?

            <asp:GridView ID="GridView_Questions" runat="server" BackColor="White"
                BorderColor="#3366CC" BorderStyle="Solid" BorderWidth="1px" CellPadding="4"
                Height="147px" Visible="False" Width="795px">
                <Columns>
                               <asp:ImageField ControlStyle-Height="220"
            ControlStyle-Width="700" DataImageUrlField="Image" HeaderText="Establishment">

                    </asp:ImageField>
         
 
                </Columns>

                <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
                <HeaderStyle BackColor="White" Font-Bold="False" ForeColor="#000066" />
                <PagerStyle BackColor="#99CCCC" ForeColor="#003399" HorizontalAlign="Left" />
                <RowStyle BackColor="White" ForeColor="#003399" />
                <SelectedRowStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
                <SortedAscendingCellStyle BackColor="#EDF6F6" />
                <SortedAscendingHeaderStyle BackColor="#0D4AC4" />
                <SortedDescendingCellStyle BackColor="#D6DFDF" />
                <SortedDescendingHeaderStyle BackColor="#002876" />
            </asp:GridView>
