Re: Beginners question: URL to page mapping? (BP 1.1.3)
I suggest upgrading first to the latest version of BuddyPress: https://codex.buddypress.org/getting-started/upgrading-from-10x/
And then using something like the Media+ plugin.
You will have to do some theme re-work for compatibility with 1.2.x, but you’ll be making it a lot easier on yourself for any changes.
If you don’t want to upgrade, it might be worth putting 1.1.3 in the thread title, to solicit more direct help.
