Re: Looking for good photo gallery
There are two available that should fit your needs.
1. Buddydev’s BP Gallery which includes photos/video/audio and is in beta right now shortly to go stable at http://buddydev.com ( this is a premium plugin and access costs $30/3 months)
2. bp album which is just photos but is free. They’ve made big strides lately and it should be available in the wp plugin repo.
