Fear not, as we unveil the comprehensive guide on How to Move Your Mac's iPhoto Library onto an External Drive.

LOVE this program! Works better than ANY other program out there that I have found to upload thousands of pictures WITH SUB-FOLDERS to SmugMug! Thank you so much for what you do! :) #happycustomer
Pausing Motion testimonialPausingMotionsmugmug
I pointed PicBackMan at a directory structure, and next time I looked - all the photos had uploaded! Pretty cool. I use SmugMug and while I really like it, the process of creating directories in is pretty laborious when you need to make 80+ at a time. This was a breeze. Thank you!
