Leaflet Maps Marker is a WordPress plugin by harmr that allows you to:
pin your favorites places with markers,
use integrated address search (Google Places API) for quickly finding your places,
choose from up to 700 custom free map icons from Maps Icons Collection,
add popup description text or images for each marker,
choose individual basemap, size and zoom level for each marker/layer map,
organize your markers in layers and
show them thanks to the Leaflet library from Cloudmade
by adding a shortcode (e.g. mapsmarker marker=”1″)] to posts or pages
through OSM/OpenStreetMap, MapQuest, OGD Vienna Maps
or any custom WMTS-map
