[developer 2000] button's icon?

[Quoted] [Quoted]          We all know we can set the button style as iconic..
[Quoted]          But I found that the icon must be *.ico and the button is very
[Quoted] ugly when your
         button is large...
         your ico  is on the center of the button and very small.
         How can we make "ico" bigger such as toolbar button of Netscape
