Sharing Images with Factories:
Open the image you want to share. Make sure it is saved as an Opacity image so it will keep the factories you add.
Select the Image > Add Factory menu item to add a factory.
In the Factories Inspector, change the Build of your new factory to the application you want to use to share it (either Mail, iChat, Transmit, Fetch, or Adium).
Enter the information about how you want to share the image (like the recipient or buddy to send it to).
Edit the rest of the Factory properties to set how you want the image to be exported.
Whenever you are ready to share the image, click the Build button for this factory.
