The only reason I don't like the FB app is because you have to go to the browser to view pics.
I like Bloo, you click on the pic and can view it right in the app. If the FB app could do that, I would come back in a heartbeat!!
I've been able to view pictures within the app for the last couple of version at least.
There seems to be some weirdness if someone shares a picture from someone else's gallery, that takes me to the browser. The original post, however, opens the picture right in the app.
How come it doesn't flip to landscape when the phone is on it's side or in the dock? Sure it used to.
