170758 Google Maps Application

First if is possible I like to have a Google Maps Application do read a FLAT DATABASE and get all necessary informations to ADD markers on Maps. Locations added on maps will to display NAME, URL, IMAGE(photo), Text and a default form to Get Directions too (from here, to here). Will be nice to have the option to choose icons for markers too. I already have a php script which show maps and directions zip code based without open a Google page, maybe can be integrated. The search feature will have to show maps by zip code, address, name or categories like Hotels names, restaurants names, all data will be retrieved from the flat database. If isn't possible to work with flat database I will to think about backup my currently flat db into Mysql. Sorry my english, pablobr
