Toolbar: How to Add bitmaps with different width

I want to add into Toolbar control the buttons with bitmaps of different width.
According to MSDN:

Quote:

---

Microsoft® Windows® assumes that all of a toolbar's bitmapped images are the same size.

But if you will see, for example, Google toolbar you can find out that it has buttons with different width of bitmaps.
How can I achieve the similar behavior?

Actually I want to set the bitmap width of specific button to some different value than the others.

Thank You.
