Instagram is a free smartphone app that lets you share your photos with friends via the app or other social media services such as Facebook and Twitter. Although you can sign in to your Instagram account on your PC using a Web browser, you'll be limited to a basic overview of your account. Instagram does not offer a search function to find friends so you must browse directly to your friend's profile URL, or you can use an Instagram Web viewer application with search options.
If You Know Your Friend's Username
Browse to Instagram.com and log in to your account.
Open a new tab on your browser
Type "instagram.com/username" (without the quotation marks) in the address bar, replacing "username" with your friend's username. You will now be able to click on the "Follow" button to follow that person.
Finding Friends Using an Instagram Web Viewer
Enter the Web address of an Instagram Web viewer application, such as Web.stagram.com, Statigr.am or Gramfeed.com (links in Resources)
Click on the "Sign in With Instagram" button on the page.
Click "Authorize" when asked whether the app can access your basic information.
Type the name of your friend in the search box on the page and click the search icon represented by a magnifying glass.
- If you want to remove an Instagram viewer app's permissions to access your account, go to your Instagram profile by clicking on your name. Click "Edit profile" and select "Manage Applications." Click the "Revoke Access" button next to the application that you want to remove.
