Instagram’s growing up. The photo-sharing service has expanded its desktop Web presence, announcing Tuesday that users can now browse through the network on their PCs and laptops.

The Web site is pretty minimalist, only showing users the photos of people they follow and allowing them to edit their basic profile information. Users can also comment on photos in their feeds, and endorse them. Clicking on a friends’ username will also lead to his or her Web profile, which displays all of the photos they’ve shared on Instagram.

But there's no search or browse function to look at public photos or even a place for users to sort through their notifications — just a simple feed of your friends’ photos, framed on a big screen.

The new site allows users to gain access to their feeds from any device, the company said, but consciously leaves out a central Instagram feature — the ability to share your own pictures.

In a blog post, Instagram co-founder Kevin Systrom said the company intentionally did not give users a way to upload photos to their profiles through the desktop, to keep the spirit of Instagram’s service intact.

“We do not offer the ability to upload from the web as Instagram is about producing photos on the go, in the real world, in realtime,” Systrom said.

To see their feeds, users can go to Instagram’s main Web site and click the “log-in” button.

(Instagram is owned by Facebook. The Washington Post Company's chief executive and chairman, Donald E. Graham, is a member of Facebook's board of directors.)
