I wrote a macro to automate a repetitive task (re-sizing pictures that I paste in from Excel).

I want to have this macro available regardless of what presentation I'm working on and to add a custom button to my toolbar to run it. Is there an equivalent of the old Excel standby of saving the macro in the Personal.xls workbook in the XLSTART folder? I couldn't find a way to hide the presentation (like I would in Excel under the Window menu), nor do I know where I would save the file in order to get it to open when I open PowerPoint.

I'm working in PowerPoint 97.

Thanks in advance.
