Flickr.NET - Bypass Flickr Authorization Page

I am uploading photos to Flickr in .NET project using Flickr.NET API Library (Flickr.NET CodePlex Link). Its working perfect. But for every request, Flickr asks my permission to authorize the app (check screenshot below):

My question: is there any way I authorize the app once for my whole life rather it asks for my permission for each photo to upload?

Solution

Once you have exchanged your request token for an access token, you can store the access token in your application's persistent memory and use the access token to make subsequent requests.
