BPDev has a paid plugin that can do the first step: http://buddydev.com/buddypress/introducing-bp-gallery-rc4-for-buddypress-time-to-get-stable-in-next-week-now/ It requires a modification to the plugin, but the details to do so are in the forums. I haven’t seen the second part yet, but I think the BP Media plugin is working on that.
