Rename filename in accordance to tag: StackedImage value

[TravelPhoto]

I've got it now and it is working without my HDR additions. Whatever happens when I've started the command the very first time, not to add the HDR info to the filename.

Thanks again, now I am able to update all of my images. But of course I will have to do some backups first.
