Capture "Save As" Pathname and Save another File.

I have an excel workbook that uses a .bmp file [a picture]. The master excel file and the .bmp file are in the same directory on the network. The excel file is "Read-Only", so the user would open it, customize it and save it on their own computer or somewhere else on the network.

They are only allowed to save it under "Save As". Once the user saves it, they would then be able to use their customized copy for future updates etc. The problem is that the .bmp file is missing from this new directory.

Is there a way to automatically save a copy of the .bmp file under the Directory specified by the user, so it's always available when the Excel workbook is opened? Or is there a way to attach the .bmp file to the excel file, so they are always saved together?

Hope someone can help me or point me in the right direction.

Thanks,
modytrane.
