Whenever I attempt to change my skin from the Skinpedia, I get the following error from minecraft.net:

Failed to save skin:
org.jets3t.service.S3ServiceException: Request Error. PUT
'/MinecraftSkins/Yarok.png' on Host 's3.amazonaws.com' @ 'Sun, 13 Feb
2011 14:27:34 GMT' -- ResponseCode: 400, ResponseStatus: Bad Request

I'm not sure what I'm doing wrong, or where the problem arises. I've changed my skin before and this has never happened.

EDIT: Nevermind, problem solved with manual upload
