Does anyone know where I can find a searchable image database where: a) the image database has a large number of images, representing a very wide range of things (people, places, objects, events, etc) b) we can search for relevant images using just keyword search terms Ideally I want to be able to use a PHP script to specify a search term, launch the search, get back images, and publish these images onto my webpage somewhere. I am willing to pay money to license such a collection/system if there are no free ones. Anyone know where I should look?
