[Action] Profile Images Import [Alternatives] PowerShell can be used for SharePoint 2010 deployments that have image present in AD and kb2394320 installed. Script and instructions detailed here. PowerShell can also be used to upload the images to a SharePoint 2010 library and alter the –PictureUrl parameter. Script and instructions detailed here. [Notes] 
A very useful feature that is limited by the need for an image name to match an account name. Some characters are also hardcoded.
