I am checking with openphoto group for adding commons as a image source. check the discussions here. https://groups.google.com/forum/#!msg/openphoto/yGpsOPJujQs/mHwsU5cC3rIJ
If it is done, we can setup a openphoto instance and make it as a gallery for users to present their photos.
Is there any tool or library in php which uses mediawiki api, to get the photos and meta data from commons?
