Imbedded Picture Names
 

Hi,
May be a silly question but I have an Excel program that imports and
clears numerous images as the user uses the tool. The images are organized
on the spreadsheet surface. I'm going to add some functionality that will
reference the picture name to cross-reference with related data. I noticed
that over time the picture names associated with the imported images continue
to increase (Ex: Picture 107059) even when they are cleared from the
spreadsheet and the program is restarted. I haven't had any problems with
this, but is there a convention to follow that is preferred with regards to
importing and clearing pictures or is there a procedure to have Excel "reset"
the image number back to some low number so I don't run into some sort of
overload in the future?

Thanks much.
