    Hi Folks,

    I had previously set up my RadRotator using a DataSource with a bound ImageURL to server path to image files.  This was working fine up until last night when our Windows update went live.  I presume it's done something with IE11 (our default browser) as the images for the rotator are now not showing.

    The rotator itself loads; the buttons are visible.  Just no images.

    When loading the webpage under Chrome, Firefox or Edge, it still works correctly.

    Does anyone know specifically what has happened to stop the images loading, and what I'll need to do to fix this?  I'm guessing it might have something to do with security around either the database or loading images directly from a server path.

    <%@ Control Language="C#" AutoEventWireup="false" CodeBehind="TransformationRotator.ascx.cs" Inherits="PNCCPortal.UI.NewsModules.TransformationRotator" %>
    <%@ Register Assembly="Telerik.Web.UI" Namespace="Telerik.Web.UI" TagPrefix="telerik" %>
    <script type="text/javascript">
        function OnClientLoad(rotator, args)
        {
            if (!rotator.autoIntervalID)
            {
                rotator.autoIntervalID = window.setInterval(function ()
                {
                    rotator.showNext(Telerik.Web.UI.RotatorScrollDirection.Left);
                }, rotator.get_frameDuration());
            }
        }
    </script>
    <telerik:RadRotator RenderMode="Lightweight" Width="1963px" Height="450px" ItemWidth="1903px" ItemHeight="450px" ID="rotTransformation"
                        runat="server" RotatorType="Buttons" DataSourceID="dsTransformation" Style="margin: -5px 0 0 -388px" FrameDuration="20000"
                        OnClientLoad="OnClientLoad">
        <ItemTemplate>
            <a href='<%# DataBinder.Eval(Container.DataItem, "URLLink") %>'>
                <asp:Image runat="server" ID="MarqueeImage" ImageUrl='<%# DataBinder.Eval(Container.DataItem, "ImagePath") %>' />
            </a>
        </ItemTemplate>
    </telerik:RadRotator>
    <asp:SqlDataSource ID="dsTransformation" runat="server" ConnectionString="server=XXXX;UID=XXXX;PWD=XXXX;database=XXXX" SelectCommand="select
        *
    from
        PNCC_MOJO_TransformationMarqeeImage
    where
        Active = 1"></asp:SqlDataSource>

    Hello Kenyon,

    It seems to be an issue introduced in the Security Update for Internet Explorer and Microsoft are aware of it and are looking into it: https://support.microsoft.com/en-us/help/4486474/cumulative-security-update-for-internet-explorer-february-12-2019

    Issue: After you install this security update, Internet Explorer may not load images that have a backslash (\) in their relative source path. 

    Solution: Change the backslash (\) to a forward slash (/) in the relative path of the image element. 
    Or:
    Change the relative path to a full URL path. 

    Microsoft is working on a resolution and will provide an update in an upcoming release.

    Hi Peter,

    Thanks for that, it's good to know it's being worked on.  I've tried a couple of the packages but unfortunately we're on Windows 10 and none of them appear to work at my end.

    Cheers,
    Kenyon.

    After a little Googling I've seen a Windows 10 update was released on the 20th that should fix the issue.  I'll have a talk with our system support guys about when they're planning on rolling it out to the wider user base.

    I think we may as well mark this as resolved now.

    Cheers,
    Kenyon.
