Very cool - thanks for the info - I have a hiking map in mind I'd really like to scan. I'll be playing with this once I get the time, and may be able to make a rename script, as renaming by hand offends my sensibilities .

Question - are the zoom levels 1:1 - if 14 is equivalent to MM 3, is 13 (or 15) 2? I'd want to go down to 1 or 2.
