But one of the downsides of instagram is its lack of web presence. You don’t get a profile, you have to have the link for each photo you’ve uploaded from wherever you’ve uploaded it to (be it Facebook, Twitter, Tumblr, Flickr, etc) to get to the photo’s native location on the instagram server.
Instagram is rumoured to be working on a nice web interface. It’s coming. So they say. But in the meantime check out this neat little 3rd party service called webstagram. All you need is the person’s username and you’ve got a nice little instagram profile.
