Hi Vik,
Please refer to this
sample application attached here which shows how large (32x32) icons can be used in XPMenus. Let me know if you are using an older version of Essential Suite.
The ''black shadow'' of the icons when used in menus is a known .NET framework issue and not a shortcoming of our controls. I am afraid there is nothing much we can do about it. Please let me know if you need any other information. Thanks for choosing Syncfusion products.
