Our friend, Lance at Rusty Pickle shared with us a great way to access your iPhoto straight from MemoryMixer.
1- Open Finder and go to your "Picture" Folder.
2- Right Mouse Click (or ctrl + Mouse Click) on "iPhoto Library" and select "Show Package Contents". Notice a new Finder window will display.
5- Drag your new folder "Originals Alias" to your Desktop or to your "Picture folder" which should be displaying in your other finder window.
