Aquí te muestro el código de la clase RichMenuItem, con esa clase podrás crear elementos de menús que utilicen imágens, y de una forma bastante fácil, por supuesto esta clase solo es necesaria para las versiones 2002 y 2003 de Visual Basic y de C#, ya que la versión 2005 incluye menús en los que se pueden indicar las imágenes a usar.
Del código mostrado, la clase de C# es la original incluida en SharpDevelop, pero la de Visual Basic está modificada para aceptar otras propiedades y formas de mostrarlo, (lee los comentarios para saber cuales son esas diferencias).
Al final de esta página tienes la autorización del autor de la clase de C# para que la publique sin estar atado a la licencia GPL que se aplica al proyecto SharpDevelop y a cada uno de sus componentes.
En esta otra página tienes un ejemplo para Visual Basic 2003 de cómo usar esa clase.
En ese mismo ejemplo puedes encontrar una clase para extraer iconos desde una imagen con varios iconos, esas imágenes serán las que se usen en los menús.
En esa página con el ejemplo, también hay una clase para seleccionar el dibujo a mostrar a partir de una imagen con varios iconos (también se incluye esa imagen en esa página), de forma que sea fácil indicar el icono que quieres usar.Espero que lo disfrutes.
Nos vemos.

El código para VB .NET
Este es el código de la clase RichMenuItem con algunas modificaciones sobre el original de C#.

Como notarás hace tiempo de esto... y hasta ahora no lo había publicado... en fin cosas de las pocas neuronas que tengo, y si no llega a ser por una pregunta en los grupos de noticias, pues ni me hubiese acordado, ya que tanto en Visual Basic 2005 como Visual C# 2005 se incluye la posibilidad de usar iconos en los menús.

Sorry, I clicked send to fast :(
Yes you can use the RichMenuItem class in a sample without the GPL applied.
(thanx that you ask, I give code away, if people just >ask< :))
