microsoft excel icons

I created a dozen or so macros in Microsoft Excel, and use them regularly. Also, I created from scratch toolbar icons to go with each macro. The system worked great. I just migrated to a new laptop and the problem is I am unable to find the icons or a file with the icons in it on the new laptop. Does anyone know a way to find the previous icon file or what it might have been named(I found the macro file on new computer and moved it to the XLSTART folder)
I’m using MS Office Excel Professional Edition 2003
Thanks
