trouble with asp.net Image

I'm attempting to select an image path from a database and  load it into an asp Image, but the image doesn't show.
<asp:FormView ID="FormView1" runat="server"  DataSourceID="SqlDataSource1" Width="100%" >
        <ItemTemplate>
            <table style="width: 100%">
                <tr>
                    <td>
                        
                        <asp:Image ID="Image1" runat="server" Width="1000px" ImageUrl='FieldPics/<%# Eval("relPath") %>' />
                        <%--<img src='FieldPics/<%# Eval("relPath") %>' width="1000px" id="Image1" alt="myPic" />--%>
                        <asp:Label ID="Label1" runat="server" Font-Bold="True" Text='<%# Eval("photoBy") %>' Font-Names="Verdana" Font-Size="12px"></asp:Label>
                    </td>
                </tr>
                <tr>
                    <td>
                        <asp:Button ID="btnRotLeft" runat="server" Text="Rotate Left" />
                        <asp:Button ID="btnRotRight" runat="server" Text="Rotate Right" OnClick="btnRotRight_Click" />
                    </td>
                </tr>                
            </table>
        </ItemTemplate>
    </asp:FormView>



    <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionString %>"
        SelectCommand="SELECT replace(relPath,'\', '/') as relPath, picDateTime, county, quad, photoBy, photoDesc, fTrackID FROM fieldPics WHERE id = @PhotoID">
        <SelectParameters>
            <asp:QueryStringParameter Name="PhotoID" QueryStringField="photoid" Type="Int32" />
        </SelectParameters>
    </asp:SqlDataSource>

If I do this with an html image, it will show...
<img src='FieldPics/<%# Eval("relPath") %>' width="1000px" id="Image1" alt="myPic" />

But I'm trying to rotate the image with ImageMagick and then I can't do this....
protected void btnRotRight_Click(object sender, EventArgs e)
    {
        Image img = (Image)FormView1.FindControl("Image1");
        string imgSrc = img.ImageUrl;
        ClientScript.RegisterStartupScript(this.GetType(), "error", string.Format("alert('{0}');", imgSrc), true);
        string arg = @"convert """ + Server.MapPath(imgSrc) + @""" -rotate 90 """ + Server.MapPath(imgSrc) + @"""";
        callImgMagick(arg);
        displayImg(imgSrc, 5000);
    }

I also can't get a proper ImageUrl into my ImageMagick command.  It tells me I have illegal characters.  When I use window.alert to display the ImageUrl it shows 'FieldPics/<%# Eval("relPath") %>' rather than 'FieldPics/CONWAY/ATKINS/DSCN0220.JPG'
