Hi,

In the view of replies posted, I think profile pics (hereafter avatars) in colleague section are fine to have but dIefinitely not a necessity.

IMHO, here is an optimal solution:

Couldn't there be a two way option: whether i want to share my avatar in the circle, and if i want to look at other avatars?

It would be pretty effective.Lets say, I'm not interested in avatar of your colleagues, so i can turn them off or they would be in a drop down list. And say if I don't want you to see my avatar in colleagues section/list, I can turn it off from my side. So, you would only see a default avatar associated with my profile.
