Checkboxlist with Image in ASP.NET

Put the checkboxlist control on to aspx page as follows:

<asp:CheckBoxList ID="checkboxlist1" AutoPostBack="True"
RepeatDirection="Horizontal" TextAlign="Right" runat="server"
RepeatColumns = 5 ondatabound="checkboxlist1_DataBound">
</asp:CheckBoxList>

Bind the checkboklist control on codebehind as follows: 

private void FillIcons()
{
 //Fatch the record from database and contain into datatable
    if (datatable.Rows.Count > 0)
    {
        checkboxlist1.DataSource = datatable;
        checkboxlist1.DataTextField = "ImageName";
        checkboxlist1.DataValueField = "Name";
        checkboxlist1.DataBind();
    }
}

Add these lines for displaying the image. 

protected void checkboxlist1_DataBound(object sender, EventArgs e)
{
    foreach (ListItem item in checkboxlist1.Items)
    {
        item.Text = string.Format("<img src= \"{0}\" title='" + item.Value + "'/>",
        string.Format("images/{0}", item.Text), null);
    }
}
