Instagram website frames users' pictures

"Instagram, at its core, is about seeing and taking photos on-the-go," company co-founder Kevin Systrom said in a blog post.

"You can now browse your Instagram feed on the Web, just like you do on your mobile device."

Instagram.com was designed without the option of uploading images from the Internet because the service is about pictures "taken in the real world, in real time" by people on the move, according to Systrom.

Features at the website, which was launched last year with Instagram members' profiles, include being able to "like" pictures and join online conversations about images.

Facebook acquired Instagram last year. The original price was pegged at $1 billion but the final value was less because of a decline in the social network's share price.
