What does Twitpic do on your Twitter account?

[one of twenty]

I'm thinking about using Twitpic.
When I tried to log on using my Twitter account this is what it says:

This application will be able to:
Read Tweets from your timeline.
See who you follow, and follow new people.
Update your profile.
Post Tweets for you.

What exactly does this mean? What are some updates it will do to my profile? What does it mean it will post tweets for me?
I'm new to this. Any help is much appreciated.

Posting tweets for you means that technically, you are sending it through Twitpic, which puts it on Twitter for you. It doesn't post tweets or update your profile, or any of the other stuff, without you explicitly doing that action yourself. Twitpic and other things like Echofon are merely third parties that carry out the actions for you.

No it allows you to share & upload photos on your mobile & send them to Twitter via Twitpic it is also an application produced by Twitter itself so I don't see why you don't trust it!!! :-)

All it means is it will post links to the uploaded pic with your approval. Its like terms and agreements on a program, it doesnt mean anything stop worrying.
