LifeHacker has this super cool feature right now on how you can set your desktop background images to sync with your Instagram photos. Essentially what you’re doing is you’re backing up all your Instagram images to Dropbox and syncing them via the Dropbox applet on your computer. Then you tell your OS to switch the background out from a particular folder and then you’re set after you set it to automatically rotate out.
But it’s a lot more than that, there is the whole process of your new stream of Instagram images needing to be backed up too. And for that, it’s very much worth heading over to LifeHacker.
