Changed Twitter avatar and does not change on TwitPic (even after posting new photo)

I changed my Twitter avatar and it won't change on TwitPic, even after posting a new photo.

TwitPic displayed my avatar just fine before. Then I changed it on Twitter and TwitPic is still looking for the old avatar image (based on the file name it is looking for). When I look at the HTML on TwitPic, I can see the the old file name referenced.

My TwitPic page now shows a broken image for the avatar. See http://twitpic.com/photos/RyanFarley

Uses src for img as http://s3.amazonaws.com/twitter_produ... (This is the old image for my Twitter avatar, which is no longer there after changing it).

The correct src should be http://s3.amazonaws.com/twitter_produ...

I have posted two pics to TwitPic after making the change (once from phone, and once from twitpic.com site itself).

Thanks.
