Thanks, that worked. I changed one line to

puts "#{tag}:         #{photo[tag]}"

since it errored to begin with. Maybe a copying error.

I had looked at the docs but I didn't know what to look for (still 
don't). I'm not confortable enough with Ruby nomenclature to be able to 
figure out I need a method tags and I don't see where'd I'd find that in 
the docs and know what it would do.

Thanks
