Facebook privacy settings?

[Query]

I made a group for certain people on my Facebook. They are the only ones that can see my wall and pictures. Nobody else can.

However if I comment on one of my pictures, it comes up on my peoples news feed who shouldn't be able to see it! Frustrating!

Also if I comment on a friends photo, it does the same. Comes up on everyone's news feed.

I'm pretty sure I've set all the privacy settings correctly to how I want them. Is this just a loophole in Facebook's system?


Any help would be appreciated.
Never mind about what I want people to see. The last thing I need is advice like that thank you very much. I asked a question in regards to it being a loophole or not. If you don't have an answer or suggestion, don't reply.
