The Obama White House has its own  stream on Flickr, the public photo-sharing Web site. It's a must-visit for administration watchers, since it is regularly updated with some candid, behind the scenes shots of the president in action.

Today, though, is an example of why using such an open-ended platform might not always be in the best interest of the administration. This photo was posted of President Obama chatting with Speaker Nancy Pelosi as the two walked from the Oval Office to the Rose Garden for this morning's announcement on new emissions standards. Take a look at some of the comments that visitors have since posted, taking aim at the embattled Democratic leader in the House:

• "Nancy, just shut up for God's sake, you're starting to make Joe look like the second dumbest person in DC"
• "Please, President Obama, reel her in and put her on a short leash"
• "Glad to see he's showing her the door. Maybe she'll get the hint."

At his press briefing today, Robert Gibbs denied that Pelosi's inclusion in today's event was meant to be an additional signal of support as she faces continued criticism over her remarks about the CIA.
