Created Unassigned: AjaxFileUpload black box [27587]

Hi there,
im using DotNetNuke: 07.01.02 (356)
I want to implement AjaxFileUpload control so in my ascx file i add lines:
```
<%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" tagprefix="ajaxToolKit" %>

<ajaxToolkit:AjaxFileUpload ID="AjaxFileUpload1" AllowedFileTypes="jpg,jpeg" MaximumNumberOfFiles=1 runat="server"/>
```

and ofcourse i added ajaxcontroltoolkit.dll to resources in my project. In my web.config added this line (working on IIS7.5):

<system.webServer>
....
<validation validateIntegratedModeConfiguration="false" />
<handlers>
<add name="AjaxFileUploadHandler" verb="*"
path="AjaxFileUploadHandler.axd"
type="AjaxControlToolkit.AjaxFileUploadHandler,
AjaxControlToolkit"/>
</handlers>
</system.webServer>

But everything i see is only black button inside border, nothing else :/ maybe im doing something wrong ? pls help me, im frustrated :D
