Create button on Toolbar linked to macro

Hi
I want to create a button on the toolbar that is linked to a macro.
I also want to customize the button with a "smiley"
How can I do this?
Thanks

Have the workbook with the macro that you wish to attach to the button open

Tools Menu > Options > Commands

Under the Categories list find Macros
Click on Custom Button Icon, Whilst hoding down left mouse button drag icon upto the tool bar

Right click on new toolbar Icon, Select Assign Macro
Select required macro from presented list

When right clicking on Icon you also get options to Change, edit Icon

I hope this helps you
