Thomas,
Thanks for this, but this is a questionable feature in my opinion. My primary camera is my Nikon D800, and I almost never allow its full size 7360 x 4912 images to upload to SmugMug, opting for a fit within 4288 x 4288 instead (the size of my images from my long used D300).
Also, I sometimes upload from a different library to SmugMug, and don't want all albums pulled into my primary library. The FB sync has already presented problems when wanting to connect to FB when remote, but not wanting to sync to a library that is limited to the internal drive.
