I found this on github and would like to share it with everyone. https://github.com/Piwigo https://github.com/Piwigo/Piwigo http://piwigo.org/ I've been using it for a bit now and i can say its pretty good all things considered. It has an api, it has an extension submission system. It has an active community (although some extension/plugins could use a bit of updating e.g.(url uploading))
