Instaport and InstaBackup Help Transfer Photos from Instagram
Instaport is a nice and easy to use website that lets you download all of your pictures in a zip file. The service will also be adding the ability to shift your photos directly over to Facebook, Flickr or an RSS feed. The downside is that it's pretty busy right now, and exports are taking quite a bit of time.
If you're a Mac user, InstaBackup is an alternative that might work out well. Simply download the app, install and then download your pictures.
