AcidFree Gallery of All User Galleries

I am using the Acidfree Album Module with user galleries. Each user's gallery can be viewed through /user/acidfree. But I don't want to view one at a time like that. Does anyone know of a way that I can make a page that shows every user's galleries on one page, so that all submitted user content can be reached in one place? I have come across this website Commonpath.org and it appears that they have accomplished this.

Thanks for helping.
