I released special photo gallery where photos are sorted by countries and accesible by simple map. Easy to use, nice to see. Let’s look screenshots.
First version of interactive map gallery is now available -> here <-
This awsome application allows save photos under countries. In a simple map you can see countries you have already visited (for which countries you created gallery) – visited countries have different color. You can also show all photos related to chosen country. Photos are shown in gallery (4×4 matrix) or you can see one photo and move to next or previous photo.
See screenshots:
