we are using the plug-in and LOVE it - and so do our 1,250+ members!
When we (!) broke the plugin by moving the website to a different domain and URL (i.e. moving away from the NSA from the USA to the Netherlands), the maker responded promptly from around the world (Australia) to our support request (cry for help?) and helped us fix the issue quickly - which saved our members thousands of pictures already uploaded: there really is no real alternative to BuddyPress Profile Galleries.
Awesome support, awesome plug-in!!!
We gladly donated US$25 voluntarily for the help!
