Hi Kenneth,

 

Thanks for your help. I've changed my image selector to using the gallery as your code suggested and it worked. I did make some changes as I had to include many instances of the images selector in a single page. Below is my final codes for all to reference.

 

<table border="0" cellpadding="0" cellspacing="0">
<tr>
 <td valign="top">
        <div style="position:absolute;z-index:-100">
   <CE:Editor id="HtmlEditor" URLType="SiteRelative" UseRelativeLinks="true" runat="server" Width="1" Height="1" AutoConfigure="None" ShowHtmlMode="False" ShowPreviewMode="False" EnableContextMenu="false" ShowGroupMenuImage="False" ShowBottomBar="False" BackColor="White" BorderColor="White"></CE:Editor><div style="display:none"><asp:TextBox ID="uiSource" runat="server" Text="foo" /></div>
  </div>
  <asp:TextBox id="imageFld" runat="server" />
  <INPUT type="button" value="Select Image" class="<%=styleFile %>" onclick="<%=HtmlEditor.ClientID%>callInsertImage()" id="Insert Image" NAME="Insert Image">
      
 </td>
</tr>
</table>
<script language="javascript">
    function <%=HtmlEditor.ClientID%>callInsertImage()
    {
     var editor1 = document.getElementById('<%=HtmlEditor.ClientID%>');
        editor1.FocusDocument();
        var editdoc = editor1.GetDocument();
        editor1.SetHTML("");
        editor1.ExecCommand('ImageGalleryByBrowsing');
        <%=HtmlEditor.ClientID%>InputImageURL();
    }
    function <%=HtmlEditor.ClientID%>InputImageURL()
    {
        var editor1 = document.getElementById('<%=HtmlEditor.ClientID%>');
        editor1.FocusDocument();
        var editdoc = editor1.GetDocument();
        var imgs = editdoc.images;
        if(imgs.length>0)
        {
            var path1=imgs[imgs.length-1].src.split('cmsresource/');
            editor1.ExecCommand('new');
            document.getElementById('<%=imageFld.ClientID%>').value = path1[1];
            document.getElementById('<%=uiSource.ClientID%>').value = path1[1];
            document.getElementById('<%=imageFld.ClientID%>').focus();
        }
        else
        {
            setTimeout(<%=HtmlEditor.ClientID%>InputImageURL,500);
        }
    }
</script>
