I have now created four script variations for the options mentioned in #1, #2, #3A and #4A above... Once I have your reply I'll be able to finish testing and post the final code.

Where should the script save the two new files to?

#1: A fixed location such as the Desktop?

#2: In the same directory as the source file? 

#3: In a new sub-folder under the source file directory? If so what name for the folder? #3A: Is this one common sub-folder for both files, or #3B: a separate sub-folder for each file format, under a parent sub-folder?

#4A: In a new, different variable user-selected location? #4B: Optionally writing to sub-folders, as in the previous points #3A or #3B?

The PSD save is easy enough, however, for the JPEG, is this the equivalent of File/Save As or File/Export...? What quality level and other settings? Should the JPEG version be converted to the sRGB ICC colour profile for possible online use, maintaining the original ICC colour profile for the PSD and source file?

Here is some placeholder code for the naming, to be incorporated into the file saving code once the save location and options are known.
