Bulkr is an Adobe AIR application that can download all of your photos in your Flickr account in several formats like thumbnail, small, medium, large and original. It can also download photos by Set or your Favorites photo saved in Flickr. To use Bulkr, your system must have adobe AIR and you need to give authorize permission to Bulkr in Flickr.

Twitgoo is an online photo sharing for Twitter that allows you to upload and share photos in your Twitter. All you need is to login with your Twitter account.

Twitgoo is similar to Twitpic, a similar service for twitter that I published before.
