Is there a way to post without being logged in?

How to get details of current user from Google APIs

I am sure that I am being very blind or stupid somewhere along the way but I have looked for this answer for a while and haven't come up with anything!
I have been working on getting my actionscript app working with Google's Oauth mechanisms which is all working great now but I can't for the life of me work out how to get details on the currently logged in user.
I want to get get the user's name (alias or full name I don't care) and a thumbnail url to display at the top of my app to make it clear who is logged in.
I have looked in general google api docs, drive docs and youTube docs and not found it anywhere...
I'm sure this is a really easy answer for someone to give!
Thanks
Add this to the scope -
https://www.googleapis.com/
auth/userinfo.profile
And after authorization is
done, get the information
from - https://
www.googleapis.com/oauth2/
v1/userinfo?alt=json
It has loads of stuff -
including name, public profile
url, gender, photo etc.

Instagram Login

I'm new to the Instagram API and I am very interested in using it to create a login for a site I am building as another option for the user to get access. I've had a brief look at the documentation but still have no real understanding on how this could be achieved. Any help/links/documentation would be very helpful.
Did you see this documentation? It is really spot-on so I would recommend taking a look and then if you still have specific questions about it just edit your question and I'll see if I can answer them.
