Button with image and empty string in Revit API

Question

I am creating a new tab with some stacked buttons in revit. I need to place a button without text such as the attached image: .

I am using the following code:

RibbonPanel panelMenu6 = application.CreateRibbonPanel(tabName, panelNameMenu6);

//create large buttons
PushButtonData Button23 = new PushButtonData("Button 23", "Button 23", directoryName + @"\pyRevit.dll", "pyRevit.TheCommand");
PushButton button23 = panelMenu6.AddItem(Button23) as PushButton;
button23.LargeImage = new BitmapImage(new Uri(directoryName + "\\Icons Resources\\Button 17 -bulleted-list-16 (2).png"));

//create small buttons
PushButtonData Button24 = new PushButtonData("Button 24", "Button 24", directoryName + @"\pyRevit.dll", "pyRevit.TheCommand");
Button24.Image = new BitmapImage(new Uri(directoryName + "\\Icons Resources\\Button 23 -address-16 (2).png"));

PushButtonData Button25 = new PushButtonData("Button 25", "Button 25", directoryName + @"\pyRevit.dll", "pyRevit.TheCommand");
Button25.Image = new BitmapImage(new Uri(directoryName + "\\Icons Resources\\Button 24 -paint-palette-16 (2).png"));
panelMenu6.AddStackedItems(Button24, Button25);

I tried to send an empty string instead of "button 25" but I receive an exception "The value cannot be empty. Parameter name: text".

That's the code when I receive the error. For instance, Button 24 without text:

PushButtonData Button24 = new PushButtonData("Button 24", **""**, directoryName + @"\pyRevit.dll", "pyRevit.TheCommand");

I try to create a pushbutton such as those in the attached pic 1. Image only and no text

Thanks to this blog I was able to create buttons without text. here is the code

using AW = Autodesk.Windows;
/// <summary>
    /// Each item shall be converted into Autodesk windows item
    /// </summary>
    /// <param name="tabName"></param>
    /// <param name="panelName"></param>
    /// <param name="itemName"></param>
    /// <returns></returns>
    public AW.RibbonItem GetButton(string tabName, string panelName, string itemName)
    {
        AW.RibbonControl ribbon = AW.ComponentManager.Ribbon;
        foreach (AW.RibbonTab tab in ribbon.Tabs)
        {
            if (tab.Name == tabName)
            {
                foreach (AW.RibbonPanel panel in tab.Panels)
                {
                    if (panel.Source.Title == panelName)
                    {
                        return panel.FindItem("CustomCtrl_%CustomCtrl_%"
                          + tabName + "%" + panelName + "%" + itemName,
                          true) as AW.RibbonItem;
                    }
                }
            }
        }
        return null;
    }
    /// <summary>
    /// A List contains items which shall be without text
    /// after converting each item to autodesk windows item using getbutton method
    /// set the text display to false
    /// and set the size to large
    /// </summary>
    /// <param name="ribbonItem"></param>
    /// <param name="tabName"></param>
    /// <param name="panelName"></param>
    public void editNoTextButtons(IList<RibbonItem> ribbonItem, string tabName, string panelName)
    {
        foreach (var item in ribbonItem)
        {
            var adwinbutton = GetButton(tabName, panelName, item.Name);
            adwinbutton.ShowText = false;
            adwinbutton.Size = Autodesk.Windows.RibbonItemSize.Large;

        }
    }

And that's how it looks like
