Faces is an OS X desktop application that manages your profile picture across your Twitter account(s). After linking your account, Faces will pull down your current avatar and display it in the grid and from there you can add any image to the grid and upload them to your account(s) with a simple drag and drop.
Faces is a beta application and currently requires OS X 10.6 and an active Twitter account. The app will remain free for the 1.0 cycle and will remain in beta until I get OAuth implemented before the June cutoff for basic auth via Twitter's API.
You can download the latest here (ver 1.0b7)
Download temporarily removed due to issues at Twitter with profile images, see this update
