Yes, you need. You can check oAuth. Below is the link:

hello shweta,
Is there is authentication token is require to upload a image in the picasa. Please Provide some examples of private Feed.

Hi RJ Gowtham,
I didn't get chance to go through your code complete, but I guess you may be using the basic feed, which are always readonly. Try using a feed URL ending in private/full or private/full-noattendees.
