Instagram announced today that they are (finally) rolling out a web presence and giving users profile pages. Up to now, all you have been able to do on their website is setup profiles and download apps.
Soon, all users will be able to access their pictures and profiles via the web. Currently, there are few users that have been setup, but Instagram says it will be rolled out to everyone over the next few days.
Once you are setup, accessing your Instagram web profile is easy. Just go to www.instagram.com/youraccountname and you will see your profile.
Of course, in the meantime, you kind of already have an Instagram web profile. Try out one of my favorite web apps, Statigr.am for access to your photos, friends, feeds and analytics. It really is an awesome app for account management.
