Creating or updating ImageList for ustom Icons in Visual Studio Extension

Hi,

I have created a Visual Studio Extension which has custom menus. I would like to have custom Icons for the menus.

I read through couple of articles, found that ImageList has to be created or existing imagelist (Images_32bit.bmp) which comes part of Visual Studio extension package. But I do not know how do we add images to this existing Images_32bit or create a new ImageList. As I am little new to this development.

It will be great if anyone can help me how to create new imagelist using Visual Studio or if not Visual Studio which other tools helps to do so and how to achieve it.

Thanks in Advance

Regards,
