I am adding images to my sitemap, I got 2 problems:My image alt attribute is like: The Old Square, Prague, Czech Republic or Hot dog with Prague's sausage, Czech Republic. I decided to skip image:title and put them in the image:caption is it good idea?Every photo has GPS marker, like: 43.8462,10.5031116667,17.6805 (lat,lon,alt). But image:geo_location attribute is a text field, can I put a gps coord. there in some way? I've read about Reverse geocoding but it is not accurate, should I use it or better ignor this attribute? Is it useful? In my case I need something like Cityname, Countryname but is it useful for SEO?Note: Reverse geocoding is not an exact science. The geocoder will  attempt to find the closest addressable location within a certain  tolerance.
