Instagram shut down its Twitter integration last week, which means Instagram photos no longer show up in Twitter directly and instead you have to follow a link. InstaTwit is an extension which allows Instagram photos to show up in Twitter the way they used to be.
The Chrome and Safari versions of the extension are up and running. However it isn't available for Firefox, at least for now.

To be honest I don't like at all the vintage photos of Instagram that are all over the web. I am just posting it because I know that many of you do like them! Oh, Twitter has also published its own photo filters!
