how to create menu shortcut to insert specific picture

[msworddave]

I know this is possible because I've done it before. But I can't figure out how I did it and the "help" function isn't helping.

I want to create an item in my "Insert" menu that automatically inserts a specific picture (in this case, a scanned version of my signature). I know how to add items to menus, for example, "Insert Picture from File" but how do I add insert that particular picture from file?

Thanks in advance for your help.
