Twabbit v 1.3.1.70 gets image upload to Skydrive.

The latest iteration of Twabbit adds support for Skydrive image upload, thus letting you save your pictures to Microsoft cloud storage. After installing the update, you can set Twabbit to automatically upload the pictures you twit about to Skydrive. To do so, tap ... in Twabbit and select Settings. Swipe until you reach the Picture screen. Tap "select photo upload service" and choose SkyDrive from the list. That's it. 

The change log also mentions support for YouTube video preview. I was not able to test that one out yet, but will do so as soon as I get a video in my timeline. 

Twabbit is available on the store @ $1.49 with a trial.
