Multiply previously announced that they are chopping off some features by December 1, 2012. As promised, they started to release methods and tools to get/migrate your content from your account.
The "Download media" option would have been the bomb, but it requires installing plugins for your browser for easier downloading. It also doesn't include Folder/Album information, so the photos are all mixed up :(
I'll try and review the Blogger and Tumblr exports soon.
Update 1: Chrome + Download Master works, but it keeps displaying "Allow" "Deny" buttons for multiple downloads. Some occasional "Kill Task" and "Wait" prompts show up too. Maybe Firefox would to this better :(
