Displaying image on a separate page - asp.net

Question

I have a image datatype which on click of a linkbutton needs to be displayed on a seperate page
aspx page
detail view:
<asp:TemplateField HeaderText="Evidence (if any)">
<ItemTemplate>
<asp:LinkButton ID="lbEvidence" runat="server"
Text='<%# DataBinder.Eval(Container.DataItem, "Evidence").ToString() == String.Empty ? "None" : DataBinder.Eval(Container.DataItem, "Evidence")%>'
CommandName="Select" CommandArgument = '<%# DataBinder.Eval(Container.DataItem, "Complaint_Id") %>'> </asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
ImageHandler.ashx
<%# WebHandler Language="C#" Class="FMMadminModule.imageHandler" %>
using System;
using System.Web;
using System.Data;
using System.Web.SessionState;
namespace FMMadminModule
{
public class imageHandler : IHttpHandler, IReadOnlySessionState
{
DataTable dt;
int key;
byte[] imageOut;
public void ProcessRequest(HttpContext context)
{
HttpResponse response = context.Response;
HttpRequest request = context.Request;
context.Response.ContentType = "image/jpeg";
response.BufferOutput = false;
// get the key, the index into the DataTable
key = Convert.ToInt32(request.QueryString["Complaint_ID"]);
// Prepare the datatable to hold the SNo key and the jpeg image, which will be written out
dt = new DataTable();
dt = (DataTable)context.Session["dt"];
if (!dt.Rows[key]["Evidence"].Equals(null))
{
imageOut = (byte[])dt.Rows[key]["Evidence"];
response.OutputStream.Write(imageOut, 0, imageOut.Length);
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
}
How would I display the image on a separate page?
This is how aspx.cs looks like
protected void dvResolveComplaint_ItemCommand(object sender, DetailsViewCommandEventArgs e)
{
if (e.CommandName == "Select")
{
DetailsViewRow row = dvResolveComplaint.Rows[5];
//String RowId = (e.NewSelectedIndex).ToString();
Type csType = this.GetType();
String strScript = "<script> ";
strScript += #"var newWindow = window.open('imageHandler.ashx?Complaint_ID=" + e.CommandArgument + #"', 'Evidence', ' height=450, center:yes, width=600, status=no, resizable= yes, menubar=no, toolbar=no, location=yes, scrollbars=no, status=no')";
strScript += "</script>";
ClientScript.RegisterClientScriptBlock(csType, "ViewEvidence", strScript);
dvResolveComplaint.Attributes.Add("OnClick", strScript);
}
}

this is way overcomplicated. You don't need the linkbutton at all, just write an anchor-wrapped image in your item template and call it a day, e.g.:
<img src='url_to_your_handler' alt='complaint image' />
