Email Images 1.0

Email Images is a free and simple to use Automator workflow that takes any images you select, resizes them down to 640 pixels, and attaches them to a new message in Mail.

The Action that resizes images automatically saves over the original unless you specify it being copied to a new location.

Rather than give the user the extra step of having to save the sized images, Email Images automatically saves the images to /tmp/, which makes this Workflow behave seamlessly.
