The current version of Blueprint 1.1 does not provide an upload control for images. This feature has been scheduled for the next release (Blueprint 1.2) that we will make available during this summer.
I was just testing out a few widgets and I saw flickr using the photo upload functionality of yahoo blueprint.
Is it available only for limited users or it has already been released but it is missing in documentation, I am developing an app in which I need to upload photo of a user profile to the server from blueprint. But currently I am stuck due to this. Please advise on this issue.
