Google is revamping its Local Business Centre offering, taking up the Place Pages concept it launched last September and renaming the business service Google Places. As part of that deal, it's offering to take free interior photos of selected businesses for inclusion on Place Pages (and hence Google Maps).
Google is offering to send photographers to Adelaide, Brisbane, Perth, Melbourne and Sydney. It doesn't guarantee that everyone will be included, but its decisions on where to go will be partly based on who applies, so getting all your neighbouring businesses to also apply might be a sensible step.
