Unlike other similar Twitter and Facebook webapps, Tweelay allows you to use hash tags in your tweets to control which get sent to Facebook and which don't.
Until now, when you post images to twitpic, tweetphoto
or yfrog you simply get a link to the image on Facebook.
With Tweelay you gain control over your tweets and your images. You can now assign hash tags to your Facebook Photo Albums!
Your images will be uploaded to your Facebook Albums based on your assigned tags no matter where you are.
