Enabling posting images, flairs and search

I have forgotten where to enable the ability for users to upload images in posts and how to control size limits, etc.

Also, I just noticed in your demo "Flairs". (Neat!)    Is this a post tagging feature that can be used in search filtering?
How do I configure and enable these as well?     (UPDATE:  found it under Plugin Management / Activity / Streams / Activity -  Individually configured inside each stream (eg. Recent, Profile Profile Fields, CB GroupsJive)

 

Also, I just noticed in your demo "Flairs". (Neat!) Is this a post tagging feature that can be used in search filtering?

Yup, it's basically post tagging/flair system. Posts can be filtered by their selected flair. Flair can also apply effects to posts. So for example Adult and Spoiler require clicking to view a post.

Oh neat, sort of like those blurred "viewer discretion" warnings that appear in posts on social media.

Are the Adult and Spoiler already preconfigured to do that? 

And where would I enable the search function?  I'm at a loss for where to set that up.
(Found it: Activity/Stream/Activity/(selected stream)/Filters) But I have a follow-up question:  How do I have the search function inside a group only search for posts within that group?  The Stream I selected in the GroupJive/Configuration/Integrations is CB Group Jive, but when I tested out the search (a member's name) inside the group, it pulled in posts from "Recent Activity" that were not posted in the group.

Also, I don't recall how to enable the ability to upload images (both in activity and within Groups).  In the case of Group, I don't necessarily need the Photo tab.

Thanks!
