You can certainly use your 16x16 picture for the icon property of a button,
but nothing larger than that on a commandbar.

It Excel 2007 you can use 'Gallery' for your own pictures in your
customized Ribbon.

Hi,
Is it possible to use a custom image for excel toolbar? I mean using
external picture such as .png, .img...etc. The toolbar was created in xla
format using vba.

Thanks.
