Lack of ImageList in MenuStrip and performance issues

MenuStrip doesn't support using ImageList images.

What are performance issues of this? Are there chances of using t开发者_JAVA技巧oo much GDI resources and slow-downs? How many items should be considered acceptable, after which one should implement custom control that draws images from ImageList?

MenuStrip is a subclass of ToolStrip, which has an ImageList property... what makes you think it isn't supported ?
