Well, it was available in-game already, but now you can actually see the results of your D-pad actions.

Battlefield: Bad Company allows you to capture game play moments when playing Multi-Player.

To see your screenshots go to www.battlefield.com/badcompany and log in. Then click on "My soldier" to find the tab called "My photos." This is where your unsaved in-game photos and your personal gallery of already saved photos will appear.

To watch the screenshots of other players you can head over to the media/photo gallery page to see the latest and top rated ones. You will also be able to see other players’ screenshots when browsing their stats as soon as we launch a leaderboards functionality in the coming days.

If you want to share one of your photos with other Bad Company players you'll have to make sure to save it.

Keep in mind:
Only saved photos are shown in the Photo Gallery for "Top Rated" and "Latest Added."
Photos that you capture in-game are considered “unsaved” until you log-in to “My Soldier” and actively save them.
You can have up to 10 unsaved photos. If you take an 11th photo this will overwrite the first unsaved photo.
You can vote on other players' photos just once! But you can actually go back at a later time and change your original vote (raise or lower it).
You can't vote on your own photos.
When playing all you have to do to take a screenshot is press up on the d-pad and you will see a small message letting you know the status of your leet photography skills.
